User Authentication Token

Could someone tell me or point me in the direction of some info about how long a user remains logged into PowerApps on a device once Authenticated via their Office 365 login. How long does the Token last?  30 or 90 days?

Re: User Authentication Token

Hi @AndyRHodges,


Please check the article below:

Session timeouts for Office 365

Please refer to the Azure Active Directory part:



Modern authentication uses access tokens and refresh tokens to grant uses access to Office 365 resources using Azure Active Directory. An access token is a JSON Web Token provided after a successful authentication and is valid for 1 hour. A refresh token with a longer lifetime is also provided. When access tokens expire, Office clients use a valid refresh token to obtain a new access token. This exchange succeeds if the user’s initial authentication is still valid.

Refresh tokens are valid for 14 days, and with continuous use, they can be valid up to 90 days. After 90 days, users will be asked to re-authenticate.

Refresh tokens can be invalidated by several events such as :

  • User’s password has changed since the refresh token was issued.

  • An administrator can apply conditional access policies which restrict access to the resource the user is trying to access.

Re: User Authentication Token

Thanks for the response and lookng into this.


Sorry I may not have been clear what I meant by device  - I was talking about iOS/Android/Windows Phone.


That section doesnt seem like it would not apply to a Native App.  It mentions  -  Azure Active Directory(Used by Office 2013 Windows clients with modern authentication enabled) .


Many thanks
