Access Tokens invalid every day.

[ThatOneCat]

Over the past few days I have heard from users they are having to log in every day. Not sure what is going on as we haven't changed anything. Thanks

We have had a bunch of our access tokens become invalid for some users daily. Not sure what is going on.

Are you using the Authorization Code or Implicit Grant flow?

[ThatOneCat]

Implicit with prompt=login.

Thanks for the response!

The only reasons for an Implicit Grant Flow access token to stop working:

1. The token expires. The default lifetime for Implicit Grant is 1 day, but apps can suggest a lifetime with `expires_in` and users can alter it on the Authorization Page.
2. If the authorization is revoked by the app or by the user.

If you have specific user ids and access tokens, send them with your client id to private support and we can investigate.

Yes, we are setting expires_in to 1 year. If I can get user_ids and access_tokens I'll let you know. Thanks!
