"Create new device password" is missing for some users

Hi folks, I got following problem and hope for some tipps where to dig.
An user wants to add a new device for sync with Nextcloud app, but the section Devices & sessions under Security only lists his already connected devices. The button for “Create new device password” is missing. I checked with the user and also using “Impersonate” - nothing there. It works with my admin account though.

I am not shure whether this is a bug or me missing something.

For better illustration see screenshots

Nextcloud version 19.0.1:
Operating system and version Debian 10.5:
Apache or nginx version 2.4.38:
PHP version 7.4.9:

Is this the first time you’ve seen this error? Y:

Sorry. I do not really understand your problem. Also i do not really understand the following text. But please read it. Perhaps it helps you.

Starting with Nextcloud 15
For password changes in external user backends the device-specific passwords are marked as invalid and once a login of the user account with the main password happens all device-specific passwords are updated and work again.


Thanks for your answer, but I do not use an external backend, it’s just a plain Nextcloud installation with MariaDB.

Okay, shameless self bump here…
In between I had different ideas to what this might be related to and tried to check it:

  • it is not admin vs. not admin
  • it is not 2FA enabled vs. not
  • with encryption I am not completely sure, but at least all my users have the same (default) settings

And last but not least: problem is still there going from 19.0.1 to 19.0.2 to 19.0.3

Anybody out there with ideas?
