Why would 1PW generate a OTP from Computer A that does not work, but the one from Computer B did work?

Question

Here is the precise scenario. I went to log in at Zoho, where I use a OTP generated by 1PW for my 2FA. I tried to log in several times from Computer A (a Windows machine) with 1PW automatically filling in the OTP and Zoho would throw an error every time that the passcode was wrong. I also entered it manually with the same result.

So I opened 1PW on Computer B (a Mac) and looked at the OTP generated there, and manually entered it on Computer A. That one Zoho accepted.

Any idea why or how that could happen? Is it likely an error on Zoho’s end or 1PW end?

Thanks!

Hello ​@UserJamesBond! 👋I'm sorry that you're running into issues signing into certain websites when using 1Password as an authenticator app for two-factor authentication. It’s important that your device’s time isn’t more than 30 seconds off since the time is used to generate the one-time password. The authentication code changes every 30 seconds, so if your device is more than 30 seconds off, you’ll see an incorrect code.The next time that you run into the issue, visit this website on each of your devices and make sure the time matches:https://time.isIf the date and time on a device doesn’t match, you can adjust it:MaciOSWindowsAndroidLet me know how that goes.-Dave
