Android Question Password for Private Sign Key

[aeric]

How complicated the password would you set? Length > 10? Mix symbols and case?

Since I will store my keystore file in "safe place", why not use the password as the file name?
E.g. my password is MyPrivateKey then I would save the file as MyPrivateKey.keystore so I would not forget it in the future.

Is this a bad idea?

Or my password is 123456789 then save the file as MyPrivateKey123456789.keystore
