Sunday night updated to the Jan security update on the Pixel 6. Prior to that, the finger print reader was working (but barely). I got distracted and forgot to check how the fingerprint recognition was working. The next day, forgot completely about the update and installed the Whitestone dome protector (which went mostly good but I've got three small bubbles, but that's another story).
After installing the dome, they recommend retraining the reader. However, even after training with multiple fingers, the reader, very, very rarely works probably less than 1% of the time if even that. Any ideas what I could try to improve the accuracy? The January update seems to have improved accuracy for most people. I just wish I had tested out the January update more thoroughly before adding the screen protector.
I bought the Dome glass,too. After replace it with the old glass protection the fingerprint was worse than before.
I trained the new, but not better.
What helped for me was to train the FPS again with more pressure of the finger on the FPS. Now it's working almost like the old protection.

Do you have to apply more pressure when logging in also or just for the training?

I just installed the Whitestone Dome yesterday. My fingerprint seemed to work the same but I went ahead and did a retrain. I think it is still close to without it (WD) except for 1 finger. I had an issue with that same finger on my old OP6T. Good Luck.
I also installed yesterday Whitestone Dome, the fingerprint reader works just like before almost every time. I never had any problems with the FPR, it only failed when I lifted the thumb to early. I did not retrain my thumb, increased Touch sensivity is still disabled. I don't know if it matters, but 4 finger profiles are my thumb.

Well, looks strange, is ultrasonic so has nothing to do with the case... i think is fake but who knows

YEAH, that was my first thought also. I could almost see it if it was a S10e but there'd have to be some serious crap going on for a case to defeat a screen reader.
Well only one way to find out buy $3 case and do it our self....

This is an old problem, which occurred 2 month after the official release of this phone to the market. I was able to repro it back in April on my S10, but after 1/2 months all had been fixed.
In every case remember that protective glass not compatible with ultrasonic fingerprint require more pressure on the screen, and this translates into less accuracy in saving and reading the finger data.

(Updated with new link.)
So it wasn't a gel case then and a screen protector. That makes more sense now as you can see how the screen protector can affect the fingerprint reader. Just tested mine to be sure and only the registered fingerprint can unlock it.

Same here. I tried all my fingers and only the 2 registered fingers can unlock my phone. I kept the factory installed screen protector on for a day before I finally couldn't stand it anymore and removed it. Even with the factory installed screen protector, I still could only unlock my phone with the 2 registered fingers.

I don't see it as a big problem when the phone first came out. If XDA is a good representation then the fingerprint reader didn't even work for the owners own fingers, much less a stranger's. ?

S10e unaffected?
If I understand the reports correctly, the following has happened:
You install a screen protector and THEN register your prints. The sensor "reads" the structure of the protector, not your prints. Hence, it does not matter, what finger is used as the protector unlocks the phone. However, this also means - as I understand it - that if you register you fingerprints with Samsung's or another protector that does not have the problem (or without any screen protecor), you are safe. The reports sound as if anybody could just unlock your phone by using a $3 screen protector. That is not the case, as I understand it. So basically, just try if you can unlock your phone with fingers you have not registered. If that does not work, you are safe.
Please correct me if I am wrong.
EDIT: The videos in the link below seem to suggest otherwise...
https://mobile.twitter.com/Sta_Light_/status/1184844865730801664
It effects the Samsung Galaxy Tab s6 which uses an optical fingerprint sensor. The ultrasonic and the optical sensors are entirely different. So it has to be a software bug. Which can be patched.

Just tried this with mine using two cases and thankfully it doesn't unlock. Weird bug
I've disabled fingerprint authentication for my payment & banking apps just to be safe and set them to use the good old pin.
Samsung will start rolling out the fix for this issue within the next 24 hours apparently.
Got the update!
I'm sorry, I posted this in another thread, but I will also ask here.
Does anyone know this:
If you are with the factory applied screen protector, do you have to also remove it and re-register your fingerprints after updating? Or this is only for other screen protectors (silicone)?
It's not very clear from the update explanation.

The initial statement from Samsung that I read said it was only for third party screen protectors. I did see another one that said all screen protectors, so yeah that is a little confusing.
The initial story I read said it was from a cheap screen protector then there was another story that said it was a cheap silicone case then it switched again to a cheap screen protector. Then the statement from Samsung was about screen protectors. Definite confusion. I removed the factory installed one after a day because I could feel the edge every time I swiped up or from the side and it annoyed me.
11-9-2021 - RETURNING DEVICE
I’ve given it some time to try screen different screen protectors but the nail in the coffin for me is Googles response to how bad the fingerprint scanner is. I can’t accept that as a answer with no foreseeable fixes or updates.
*****************************************
Tempered glass on and off....I've tried all the tips and tricks floating around from Google and YouTubers. The fingerprint scanner just seems to be bad all together. About 4/5 out of 10 times it recognizes my finger. When it does it's super slow.
A update went out last night that people are saying solved the issue...…It has not.
How have you dealt with or solved the issue at hand?
So far no problem with my fingerprint scanner.
One thing you could try (if you haven't done that already) is to make multiple scans for the same finger.
I made 2 for my right thumb, 2 for my right index finger and 1 for my left thumb. So far no problems... Hope that it will get better for you soon
I hate to be that guy, but my fp scanner is flawless on the Pixel 6 (at least as snappy as the OP6T was). Keep in mind, I don't use a screen protector.

I've no issues with it either also coming from OP6T. Registered prints twice and made sure to scan different areas including edges. Works perfectly and is quick enough for me
No issues on my end. I have a cheap screen protector on to. It's slow but it's been working. And I have the driest hands ever.
I've got a screen protector on and it always reads my index finger 100% since day 1.
But initially it read my thumb only 50% of the time, until I figured out that setting up prints initially makes all the difference.
Even before the November OTA fix (which I sideloaded as it was not coming through as OTA), I got it working.
Now its's almost as nice as on my 4a(5G) which is 100% accurate.
Here's a Link to my method.
I am using the ivoler tempered glass screen protector and I can never get the fingerprint reader to work.
If you have a functional finger print reader and using a screen protector, what brand is it?
i'm using tempered glass and can't get it to read. thinking about taking it off.

I had the same issues. The update didn't improve things either. I then had to factory reset (for other reasons) and FP reading is now running really well. This is with the 'difficult' spigen glass align master protector. Have yet to test it in daylight though and suspect it won't work quite as well.
After reading through everyone's post....didn't want to quote everyone but:
-Registered every angle of my finger whether thumb or index. 2 registered per same finger.
-Turned on Sensitive Touch or whatever it's called for Screen Protectors
-Turned Always on Display on to keep the fingerprint there without double tap
-Removed Screen Protector
-Updated phone
I'm also using ivoler tempered glass.
Don't think I'm missing anything else.
Only thing left to do that I saw someone did was go a Factory Reset.

I believe that people are struggling with the fingerprint reader.
That being said, I have had no issues with my P6. I don't have a screen protector on it. It reads my finger print 90-95% of the time when I press and hold my finger on the scanner until it unlocks (about 1 second). I've never had a in-screen reader, but it is certainly not a "tap the finger" on the reader like some phones are. If you are coming from an ultrasonic reader, you will have to reteach yourself to "touch and hold."
It reads my thumb too just fine. Be sure to watch how your thumb typically hits the sensor (for me it is more of the side of the thumb when I am holding the phone in one hand) and be sure to emphasis that area of the thumb when setting it up - but be sure to scan the entire finger/thumb too.
I've only saved my left thumb and right index finger once each (there are only "two fingerprints added" on my phone right now and everything works very reliably with either finger.

I agree. I normally put a screen protector on my phones as soon as I get them. However, I think we are just going to have to wait to see what works with the optical fingerprint scanner and what doesn't. This isn't just a P6 issue however. Tempered glass protectors (my go to choice previously) are unfortunately notoriously bad with optical scanners.

I agree, but at this time I will get frustrated with the phone and hope the screen protector works if and when I drop it.
I've had tempered glass screen protectors on optic in screen scanners. This could be a simple case of trial and error. I have more protectors coming in to see. I also have 10 days left to return this device if nothing solves the issue. Taking the screen protector off is out of the question.
The fingerprint scanner is by far my the worst thing on this phone. It's just as bad as the one on my Galaxy tab s7+. But I'm sure it can be fixed with an update. It's just ridiculously slow.
Hi all, those who are struggling with the fingerprint unlock, have you followed the instructions given when adding them? Having done it plenty of times I didn't even bother to look at them, I know best .
Thought I would have another go at adding them, this time I read the instructions and put the part of the finger on it asks for and although still not the fastest, it's far more accurate than it was before.
I guess you did not look at the other four threads on this topic either.
Fingerprint unlock is fine for me. It's not instant, but its faster than my old mate 20 pro ! I'm sure face unlock is just round the corner though.

Being required to do anything "slowly" isn't a tip. It's a bad reader, and Google needs to acknowledge it. Bad design and implementation on their part. That's it.

I have no problem with the fingerprint reader and I'm using a 3rd party screen protector on the display.
I just got the TOCOL screen protectors after having the phone for a few weeks. Once I put them on I redid my fingerprints for fun and it seems to work just as before. I didn't boost my sensitivity either.
Still no luck for me after adding the screen protector

Stop.

Try the Gadgetshieldz screen protector which I'm using for a month now, I have no issue with the fingerprint sensor as I mentioned before.
Oddly, while the reader is slower than the one on the back of my Pixel 2XL, I've had no problems with the reader at all unless I move my finger while it's trying to scan. When you guys set up your fingerprints did you follow the advice given and moved your finger so the scanner could scan different portions of the fingerprint during the setup?
Got a Spigen screen protector on and the right thumb is more hit and miss than the left thumb. Unlock rate is about 6/10 for left and 4/10 for the right thumb. They need to fix this issue, little things like this can get annoying. Came from FaceID which was instant no matter in day or total darkness.
I set my phone up straight out of the box and I haven't had a single issue with the fingerprint reader at all. Idk if it's my skin, how I place my thumb on the phone, etc.. I was honestly prepared to have it be awful from everything I've read but mine isn't

Tocol completely destroyed the ability of my FPR to recognize fingerprints, with or without sensitivity enhancement, with or without forehead fat, etc. But I do have very dry skin.

Hi all,
As many other Pixel 6 users I was struggling with FP sensor in inconsistency - failed unlocks mostly. I did worked a bit better without screen protector, but my personal experience tells me I need one, so the struggle continued.
Today I've made yet another attempt to re-scan my finger hoping to improve the experience and then I've noticed that the sensor seems to work way better if I place my finger 2-3 mm below what I would call centered over the icon on the screen.
No I wonder - is is just me + wishful thinking or maybe there is slight misaligned between the icon on the screen an actual position of the scanner. Any thoughts?
a.
Weirdly, it works on the bottom half of the FPS scanner icon, and not the top one, so it might be that the sensor is a little bellow the indicator
So it's not just me and my pixel. Nice
You should have posted in reddit instead
You might be right, but I don't use Reddit. Hope whoever might want to try this he would eventually find this thread.
It works well for me, you need to install certified only screen proyectors
Agreed, the FP issue is negligible without screen protector, it a slow yet solid scanner.
I've checked Google's list of certified screen protectors and pretty much all of these get some negative reviews from users. Not to mention all either not available or out of stock in EU.
Currently I'm using Spigen glass, not on the Google's list, but works fairly well.
As I wrote in my first post moving the finger slightly lower on the screen seems to help a lot.
Interesting observation about finger placement and sensor alignment. I'll definitely experiment with that.
I was cussing the fingerprint sensor up until March. It couldn't even enroll let alone unlock. Long, tedious story shortened... Since March after clean flashing the factory image the sensor improved a lot along with solving other screen related problems. My best enrollment results were with warm and clammy fingers from gripping a mug of hot coffee. As it is now only one finger out of four consistently unlocks, but that could just be me. Or placement. With that one finger I'm getting acceptable results with a cheap 9H screen protector (3-pack for $9) and default screen sensitivity. A screen protector 1-pack in the $25-40 range aint gonna happen.

I'm using my P6 without screen protector, and it is very slow and inaccurate for me. For reference, I'm coming from S21 and it's instantaneous and very precise.
What did it for me was that i ignored the instructions completely and did my own routine. for example, i never rolled my finger over the screen. instead i did both sides of the fingerprint just pressing multiple times and on slightly different angles.

I agree, it is a bummer. For last few years I was mostly using IOS and got used to authentication being seamless. My last Android was Pixel 2 and I admit - I've missed the experience. FP sensor is giving me some hard time, but I'm super happy with my P6. It will stay with me for longer no doubt.
I did some more testing, retraining etc. and I feel my initial thoughts are not accurate. The reason why I believed the scanner is positioned slightly below the icon on the screen was most probably due to the part of my finger that got scanned the best.
It might be due to the security reasons Google mentioned on the blog, it might also be a smaller and less accurate scanner used in P6/P6P. The outcome stays the same - you need to be very precise while registering your finger print and train your muscle memory to place your finger accurately on the screen.
The scanner on the back of the phone like to the one in Pixel 5 is not only using different tech, but it also makes obvious to a user where to put the finger. Pixel 6 makes it a bit harder, but that's about it.
With a deliberate finger positioning and some practice you can be pretty happy with FP scanner on Pixel 6.
Hi. I got a solution from this xda forum (sorry I don't have the link) but it basically resolved my fingerprint hit-miss issue. Ideally it involved:
1. Remove all the fingerprint images 8 previously made and starting afresh.
2. After removing, before registering new finger prints, first rub the thumb / finger I wanted to register on my forehead so that it collects a good amount of face-oil. Apparently the fingerprint registers well when registering the finger with an oily finger (I refer to the face oil...I have no evidence that other oils work).
3. After a good rub of the finger on your face you now go about registering the finger(s). Suggestion is to register each finger at least 2 times.
When you try using the fingerprint scanner it will work well. You may have to press in a bit (not so much) but this works pretty well.
