1Password no loger works

avatar

After updating to 2026.1.10.0 from 2025.3.30.0, 1Password will no longer connect and gives the error "Login to 1Password failed". We are not using SSO, and are using MFA. The following stack trace is produced. I have tried clearing the 1Password account setting, and re-setting it up, and still get the same message.

Adding a +1 here to monitor for a fix - same issue as OP.

Hello,

Could you please specify which MFA you're using? We haven't been able to reproduce this error internally, so that could help accelerate the situation.

Thank you

I am using Authenticator App MFA (2FAS app).

avatar

Ok thank you. I don't have any issues with 2FAS either, so we'll keep digging and let you know once we find anything.

I'm using the authenticator app as well, but with TOTP.

@Jonathan Del Signore - is there an ETA on release for the .11 release? The link showing that it is fixed goes to release notes but still at .10?

avatar

Hello,

Yes sorry it wasn't out yet, but version 2026.1.11 is now available.

Regards

@Jonathan Del Signore - UPDATE - the newest release 2026.1.11 fixed the 1Password issue for me. Hopefully, that addresses others.
