Bug description

When I am browsing my cloud, and I switch over to the Passwords app sometimes I get Error 401 unauthorized. (not every Time). I already found this thread which sounds similar but has no solution.

I am using the SAML backend for Logins.

For example the XHR Request to "https://cloud.xxx.de/index.php/apps/passwords/api/1.0/folder/show" sometimes work, sometimes errors out with 401.

I searched the Logs and did not find anything useful, only the one line.

Steps to reproduce

Not exactly reproducable.. On my cloud I do:

browse to different apps in my cloud
switch to passwords app
50:50 to get 200 or 401

Expected behavior

While I am logged in I should be authorized.

Same issue. Need to refresh and then it works.

We get the same error on our Nextcloud installation version 26.0.1.

This results to multiple "Login failed" errors and will therefore be listed in the "brute force" security of Nextcloud, which causes the network affected to be slow.

There seems to be a bug in how the app handles passwordless logins when it creates the temporary session token/tokens for browser extensions. An empty string is stored in the token as the user password instead of null. These tokens then expire after 5 minutes.

The latest nighty build (5155) contains a patch for this.

This bug should now be fixed with the latest update
