Application passwords

I’m testing a migration of Owncloud to Nextcloud.
All seems fine except the application passwords are missing on Nextcloud. Is this to be expected ? Or is something wrong ?
Owncloud 10.13.4, Nextcloud 25.0.13
2FA itself works fine.

App passwords are available from the beginning and can be defined in the security settings under “Devices and Sessions”, see e.g.

What I meant to say is this :
On my owncloud I configured a number of app-passwords.
For test I migrated that owncloud-instance to nextcloud.
When I go to “Devices and Sessions” on the migrated nextcloud, there are no app-passwords, at least for my own account, so I presumed all app-passwords were gone.
