Today I'm glad to release Google TwoFactor Authenticator on PSP.
Currently it officially supports iOS/Android/Blackberry, but here is another choice :p

You can use not only mobile phone call/email but also Google Authenticator applications.

In that picture, you see that [2c] is where secret key is input. In my application, you store secret keys to keys.txt.

# This libpuer pack contains my homebrews.
How to use:
1. copy PSP/GAME/google2fa to ms0:/PSP/GAME/google2fa (you can change directory name)
2. write secret keys to ms0:/PSP/GAME/google2fa/keys.txt
Here secret keys mean what you are supposed to input to your mobile phone.
Please write only keys.
3. adjust PSP's time using NTP (auto mode).
4. execute "Google TwoFactor Authenticator" and you will see 6 digits token!
This stores keys in raw form. Although it shouldn't be bad threat as you don't write profile name, please never lose your PSP ^^
NDS, iPodClassic, bla bla... cannot be supported as they don't have NTP feature. hehe.
