Change password on a crypted server, without effect on nextcloud client!

Hello
I just have changed the password of my cloud environment on a crypted server
I thought that people with access to this environment should change too, but
synchronization continues to take place without changing to new password

either through Nextcloud client on a PC
or direct access via a public link
or through Nextcloud application on android tablet

No need to change password !!!

The only change was asked with webdav mount

IS it normal

Regards
