Android Question Application protection via Mac Address

[khwarizmi]

Hi there

Is it safe to rely on application protection via Mac Address? Or is it penetrable and changeable.

Thanks

Thank you @Cableguy
The problem was finding a unique device id of the device itself, the problem is not just the password cracking, but another problem is that two different users are using the same login data.
The problem was solved by using Advertising id, using the answer provided by @asales and @Erel.

Or maybe the IMei number from the phone has to be uniqe.
User login with UserName and password and send it with the Imei

There is a problem with the use of the Imei, some non-original devices have been found with the same Imei!
