- investigating Jan 24, 2026, 02:21 PM UTC
We see some delays in customers claiming MFA OTP emails, but we currently see no queueing or delays from our email provider. We've seen some general reports of email delivery issues with a third party email provider. We are continuing to investigate the issue.
- investigating Jan 24, 2026, 04:20 PM UTC
A higher than normal percentage of email OTPs continue to be delayed to addresses hosted by a specific third party email provider. While customers cannot reduce this delay, they can reduce the possibility of expired OTPs which would lead to failed authentications or registrations by temporarily increasing the "Passcode Lifetime" to 30 minutes for the Email OTP provider within the MFA Policy. If this change is made, take note of the previous value so that it can be restored.
