My galaxy S6 doesn't recognize my fingerprints and asking for backup password. I don't have any backup password. How can I unlock my phone and to set backup password?

[titans30dude]

In order to have fingerprint security you had to have set a backup password in order to enable it

[dpham00]

If you forgot the password, Keep trying the fingerprint and review my fingerprint thread for tips.

After a few incorrect try on the backup password it'll ask for a login via your Google account.. Try that.

This happened to be today too (except I was able to conjure up my backup password). For the first 10 days or so, I never had the slightest issue with the finger print sensor. Now all of a sudden, it's much more flaky. Did Samsung break something?

i had some trouble about a week ago. I finally got on with Google and a Best Buy Samsung guys' help, but that didn't last, I got locked out again. We had to do a complete factory reset. Write those backup passwords somewhere. (Not in the phone) It also asked me for a numerical password that never worked.

I haven't had any problems since then.

Restart the device.

The same exact thing is happening to me as well! It was working as expected earlier today but in the past few hours the fingerprint sensor did not accept any ones it knew (I have both myself and my spouse in there in case somebody is incapacitated). It also did not accept my backup password. I have tried resetting it through google several times. It has never taken the changed passwords. Once (it has never given me the option again) I was able to get to a way to get in via my google account. I changed my backup password and then when it needed it again for other security settings it failed to recognize that one as well!

At this point about all I can think of is to go to sprint on Monday. So much for actually using my phone this weekend though.

Any other ideas? If I can get to the way to sign in with google again I could delete my fingerprints.

Believe it has to do with the recent Samsung software updates affecting the fingerprint reader. Happened to me also. Restarted device and still could not get in. After fourth or fifth mistake it comes up with Google account reset.

Thank goodness for that...

Was impressed with the reader until this happened. I will keep it though. If it happens again I will take it off.

Mine did this as well. But when I used my backup pw. It said it was wrong. Now I know that wasnt possible considering I use it for everything. It had me log in with Google after about 10 trys. When I logged in with google it had disabled the finger print scanner. I had to re set it up.

Finally got bit by the bug.

Same here today for the first time. I remembered the backup password, no chance that I can forget it.

Finally recovered with google account, got in. My saved finger print was removed and had to start all over again... well at least I got my phone back before had to call Samsung and perform the magic "wipe" routine.

Hi,

I have the edge.

I've been toying with this since I got it this afternoon.

Now I can't access my phone with fingerprint. what's worse--I have SwiftKey on, and the OS won't allow complex function like using # keypad.

My google account has numbers in it, and I can't key it in..

Not only that, I have power-save on... the screen keeps turning off.

I'm screwed.

Me too! This happened to me twice in the last 3 or 4 days. I had to use Google to get access to my phone. I deleted my old finger scans and added new ones. I could swear it didn't recognize my backup password either. I did reset it again yesterday. We'll see if or how soon this happens again.

My Google password also contains numbers and I am using SwiftKey but I was able to sign in when my finger scan didn't work.

I fixed this! I had this problem, it wouldn't recognise my fingerprint or back up password which was 100%correct, it also failed to recognise my Gmail account. I used a friends phone and logged into samsung find my mobile which has the same Gmail details and worked. From there I could unlock the screen and reset my passwords

[5.0stang88]

Here is video I recorded of the issue. Clearly you can see how it doesn't work as intended delayed response.

Hi,

I have the edge. I don't remember my backup password, and it does not accept my gmail accounts!! I have google authenticator configured on my gmail accounts! I think I'm totally screwed! Is there anyway to unlock my phone? I tried to restart it several times! I tried to unlock it through trusted device which it still requires my fingerprint! (It seems it is a not trusted device at all ha! )

Thanks

This post could be mine except for the last 3 words. I've tried to reset passwords, tried PIN, Pattern and Fingerprint but as soon as I lock the phone I have to use Samsung FMP to unlock it. I can only use the zero security swipe function. This is so aggravating.

[Randall Lind]

I give up on my fingerprint.. It would set up fine but from lock screen unable to detect. I set it up 10 times then said screw it.

[Gary Brooks II]

You have to use samsung find my mobile. I just had the SAME issue and it will unlock your phone.

[silverthornne]

I am having this problem too

Samsung Find my Mobile does not show my S6; I guess I had to have set that up on the phone itself and I never did. Google account is not working; it doesn't recognize my Google password. Is it because of 2FA? Backup password not working either and I know I have entered it correctly. How infuriating! I don't want to wipe my device!

[silverthornne]

Well, after the panic subsided, I went to my Google account and turned 2FA off. After doing that I was able to log into my device with my Google password.

I had already tried to use an app-specific password with it, so that doesn't work. This was scary and Samsung really needs to fix it quickly, or at least it needs to make it so that the backup password works!

[njdan30]

not sure if anyone answered but go to google.com/android/devicemanager and sign in send signal to lock device with your password of choice and then your phone will ask u for that password then your in

That didn't work for me. Android Device Manager popped a message that the device already had a password lock set. On the phone it did pop the message that I set with Android Device Manager but the password that I set with it didn't work.

I think that this is a pretty serious bug that Samsung needs to fix pronto. In the meantime, I don't suggest using fingerprint lock on the device.

[Helen Anne Holness Morris]

If I did a factory reset, will I be able to start afresh as though the phone has just arrived? If so,, how do i go about doing a factory reset please? I am terribly frustrated as won't recognise thumb print or the Backup Password I set (or thought I'd set)
