Authenticator app codes suddenly invalid

[Hdeoitj]

Have authenticator app codes for BW vault login in offline apps, such as Aegis and Yubico app.

Suddenly, codes from those apps are invalid for BW 2FA vault login, but can still log in with Yubikey.

How can that be?

TOTP = time-based one-time-passwords

→ Update / sync the time on the devices in question.

Thanks. I noticed the problem on iOS. Apple synchronises time in the background, using their own ntp servers.

There’s no setting to sync time in the apps i use either.

Sorry, I am speaking of the OS level. So, if you have a MacOS device, it would be: https://bitwarden.com/help/integrated-authenticator/#tab-macos-1lyVAuhrtle4QQhvFCERHy

Also, make sure your time-zone is set properly. US just changed to summer time this past weekend.

Thanks! My was set off, because i travel between several time zones for a living, and would rather just stick to GMT.

So, i turned it on and back off, which seems to have fixed it on iOS!

Remains a mystery why it stopped working on iOS MacOS and Android at the same time.

So, i shall do that procedure on all of them to see what happens.

Thank you for your attention and help!
