Question

I need to provide auto login functionality. I come up with 2 options:

1. save user name and password in file.
2. save user name and password in preferences.

Which option should I take? Which will be better?

Answer 1

Both seem viable options. However my vote goes to Preferences. Mainly because you would not have to deal with all the checked IOExceptions. The values either exist or don’t. In both cases, no exceptions at least.

Do remember to do an encryption/digest of the username/passwords before you save them.
