App Passwords

For the security of your account, when using any third-party clients, please generate an app password at Settings > Advanced > App passwords.

App passwords have most of the same abilities as the user's account password, but they're restricted from destructive actions such as account deletion or account migration. They are also restricted from creating additional app passwords.
