September 29, 2026

This release includes stability improvements and bug fixes to make Guardian more reliable at launch and when handling authentication requests.

User reviews

Account transfer problems

I have a specific account tied to your app that requires ages + multiple levels of approval to change/disconnect any current authentication apps,and not being able to transfer it to your app on another phone, makes me stick to ONE phone only. Why not create a feature that allows you to transfer connected accounts transfer to the same app on another phone like Google does for example?

Notifications Buggy

Generally a reliable authenticator, however either a recent app update or iOS update, or both, prevent the app for notifying the user properly on iPhone iOS. Checking the notifications settings for the app, it appears it has very limited configuration settings as compared to other apps.

Apple Watch

Used to work with the Apple Watch notification so I could accept it from my wrist hasn’t worked in months.

Needs a watch version

Seriously, add watch capability!

No more Apple Watch or lock screen approval

I used to be able to approve login from my Apple Watch or directly from the phone notification on the lock screen. The more recent updates have removed this very useful feature.

What devices is Auth0 Guardian compatible with?
