It has most likely been thoroughly considered by the developer, but I am curious as to why only use id instead of id (which stays the same with computer) + passcode (which can be changed)? seems to be different from most other apps.
there are certain benefits of having ID+passcode structure. For example, a permanet ID could allow a user specified passcode shared with trusted parties (for example the unattended access password in teamviewer), while the randomly generated passcode for one-off access
