> RTFM wink You have to create device passwords. [https://docs.nextcloud.com/server/10/user\_manual/session\_management.html#managing-devices](https://docs.nextcloud.com/server/10/user_manual/session_management.html#managing-devices) If two-factor authentication is enabled for your account, device-specific passwords are the only way to configure clients. The client will deny connections of clients using your login password then.
