The erase parameter is optional and defaults to ``false``.
An empty body may be passed for backwards compatibility.
The following actions are performed when deactivating an user:
- Try to unpind 3PIDs from the identity server
- Remove all 3PIDs from the homeserver
- Delete all devices and E2EE keys
- Delete all access tokens
- Delete the password hash
- Removal from all rooms the user is a member of
- Remove the user from the user directory
- Reject all pending invites
- Remove all account validity information related to the user
The following additional actions are performed during deactivation if``erase``
is set to ``true``:
- Remove the user's display name
- Remove the user's avatar URL
- Mark the user as erased
Reset password
