I can't login to my teams through passkey in android phone

Hello zikria fred, thanks for posting in the community.

The error AADSTS90023 usually means Microsoft Entra ID could not process the authentication request, and this often happens when the passkey on the Android device is not syncing correctly or is no longer recognized by the organization’s security rules. You can try removing the Microsoft passkey from your Android settings, clearing the Teams app data, and signing in again using your regular password before registering a new passkey at https://mysignins.microsoft.com. It is also helpful to update Android System WebView and Google Chrome through the Play Store, as this affects modern sign‑in methods on Android. If the issue continues, please reach out to your IT admin so they can check the request and correlation IDs in the Entra ID sign‑in logs, because the problem may be related to conditional access or a blocked authentication method in your organization.

Kind regards,

John Oli
