Been looking for a good password manager myself.
Been using LastPass for the month. Not impressed at all. The Android App is frustrating - erratic fill, automatic detection in apps is hit and miss, generally forces a manual intervention and lots of frustration. The Chrome plug-in is, at best, on par with Google's password manager. It isn't a compelling enough option. The Windows Desktop App is downright poor. Suffers from the same issues as the Android App.
EDIT: Oh - it doesn't seem to clear the android clipboard on Copy password.
Actually it's very very very far from a "few moments" and a properly generated password versus a thought up one is the difference between it taking years or minutes.
But the biggest risk with passwords is really just the repeated use of the same password and getting compromised at the lowest common denominator.
If your usage patterns are such that the risk of being compromised is reduced then that works too.
Or you've just been lucky.
If however you use one single password across the board and used something like public wifi at the airport I could gain access to all your accounts in mere minutes possibly even seconds...no matter what your password is.
