Can't login on Android App

[Aure]

Hello,

I use, and always have used, LastPass only on my Android device; suddenly I can't login in my account anymore.

I tried to recover the account and create another Master Password, it worked and I tried to login via Browser using the new Master Password and logged in.

Still, in my app I get this error upon trying to log in:

"Password not valid and connection not present, use a wireless connection or Wi-Fi"

(I have the Italian version, i roughly translate the message).

My mobile data is on and working

Thanks for the help.

Hi @Aure, welcome to the community.

Since you have confirmed that your new Master Password works on the desktop, could you please try uninstalling the app from your Android device and then reinstall it?

Hi Glenn/Aure, I'm experiencing the same problem. I have access to Lastpass on desktop, but I login to android app and it states "invalid password", I have no access to the passwords, but I have access to the menu for all settings.

I have:

• uninstalled/reinstalled the android app
• disabled lastpass authenticator app (as I thought the app login problem occurred when I turned on multifactor authentication)
• recovered and reset my master password
• removed and re-added my mobile device as a trusted device via desktop

Any assistance or guidance is greatly appreciated.

2022-3-29: Tech Support solved this problem for me. Solution below.

Couldn't login on Pixel 6 pro Android 12. Reinstall, cache clearing, nothing worked

Solution steps were taken in browser on desktop computer, not on phone (yes, problem on phone fixed through changing settings on desktop. Steps that worked:

1. In browser on desktop computer, open  LastPass vault
2. Click on Account Settings at lower left.
3. Click on "Show Advanced Settings" button (at bottom of window that came up)
4. Scroll down until you see "Password Iterations" at left (or click F3 to open browser page search  and search for "Iteratations")
5. Enter "100100" without the quotes in the box. Probably save the number that was in "Password Iterations" (if it is not already 100100) before changing it so you can go back to the previous setting if needed.
6. Click "Update" (appeared as a red button for me)
7. Wait for your vault to be re done (I watched a progress bar until it was completed).
8. Try logging in on your phone again. Worked like a charm for me. 

Hope this helps someone.

had the same issue on Pixel 6a - this solution worked, thanks for posting.

I tired that. Got this response. "Can't Update Settings
For your security, your master password iteration value must meet the LastPass minimum requirement: 600000"

I can't log into Lastpass on any of my Android devices now. Tried uninstalling\reinstalling, no help.

I have exactly the same issue - this strongly suggests a coding or environmental error outside of the user's control. Not very helpful as it should have been found on system testing before release....

I have same problem, i did the 100100 change, nothing happens when i hit update. When i log out and back in, it is still 600000. When i log onto my app on my Samsung s23+ it just tries to login, wont show anything on screen except from Security, Sharing center and Settings.

I raised a support case and then deleted the install on the android device, reinstalled the app a week later and found the issue did not occur. The support case is still marked as "in progress" so not sure what has been done or changed.

[DarrylGittins]

I found the problem for my scenario. Turns out, the Lastpass login ID is case sensitive. I don't mean the password - obviously the password will be case sensitive - I mean the user name is case sensitive. 

WTF, Lastpass? WHY?!!! Nobody else on the planet demands case sensitive user name.  And why don't your support people know this? I spent HOURS with support and they literally tried EVERYTHING but didn't think to look at the login name and whether it was the right case. 

Poor show, Lastpass.
