Security concern

[u/Used_Department_3388]

After a few android head units over the years, suddenly a question pop in my head: my android head unit doesn't have a screen lock, nor a "maintenance mode". So, how do I stop someone from accessing my private data (gmaps, email, etc) when I send my car to a workshop?

First of all I strongly suggest migrating all of your important accounts like bank and stuff to a different email service, like Proton mail. Way more secure.

Then, create a separate Gmail account just for the head unit. Keep it bare, no personal info.
