Not all features of Info Keep are apparent.
Phrases are usually much longer and harder to guess or attack than passwords.
If you don't want to use a passphrase, try to use very random passwords for your entries if possible. Since Info Keep is managing your data you don't have to remember complex passwords. The longer and more random the password is, the better. Get familiar with all of Info Keeps options. The program can be made to run exactly how you want it to.
