Are router admin-panel passwords hashed? Do they need to be?

Am I right to think that that the only way an attacker could extract a router password (hashed or not) from the router is have physical access to the router in question?

If someone just wanted to use the WiFi and didn’t care about anything else, my reasoning is if they needed physical access anyway, then they could just simply reset it manually.

Obviously if an attacker wanted to do something more sophisticated (such as spying on the logs,) they couldn’t just reset it manually, but would need to retrieve the password and login to the admin-panel.
