2FA by authentication app is not working anymore

[Greg HP]

The time is set automatically (time.apple.com) and is the same on all my devices.

What I've tried so far:

- Deactivate it for few seconds on one device and enable it again.

- Set the time manually to -1h and -2h.

- Re-init 2FA code in Bitwarden but can't complete the process.

- Re-init 2FA code in 1Password but can't complete the process.

So currently, my 2FA code is not working and I can't change it.

Note: 2FA works for other sites, it's only the one from Dropbox that doesn't work.

Hey @Greg HP! Thanks for posting on our Community today.

Are you receiving any type of errors on Dropbox itself when generating a 2FA code? 

If possible, can you please try to send your 2FA code as a text message to your mobile phone, and let me know if you have an issue doing that, as well? 

Keep me posted for more updates.

After registering the 2FA, I am asked to test it to finish the process. Then it says the code I enter is invalid.

Sorry, I can't use a phone number.

Sorry to jump in here, @Greg HP, but can you give us a bit more info on the authenticator app you're using?

Does it support the Time-based One-Time Password (TOTP) protocol, like Google Authenticator or Duo Mobile?

Any additional info you can give us would be really helpful.

I'm using Bitwarden (the time-based 2FA field), but I have the same issue with 1Password.

I just tried again while writing this message and... now it worked 😐

The only difference is the browser: this time I used Safari instead of Firefox (I couldn't log in this forum with Firefox, but I could with Safari, so I tried for the 2FA code).

Thank you for your help.

I'm happy to see that it was resolved, Greg and thanks for keeping us in the loop.

If you come across this issue again, or need anything else, let us know.

Have a great day!
