Basically, the length of a password beats randomness for both security and the ability to remember it. Current advice based on existing and future computing power is to use at least five random words in your passphrase.1

Using Passphrases at Geneseo
At first glance using a passphrase seems incompatible with our Password Controls for Geneseo Accounts however with just a few slight modifications you can use them for our services. Some options include capitalizing the a letter and adding a special character, or adding a number doing just two of those options does not hurt memorability and adds just a little bit more security while making it be accepted by our Password Controls for Geneseo Accounts.
Passphrases and password managers
If you use a password manager it is not necessary to make all your passwords passphrases, in fact on some sites in may be impossible due to them limiting the length of your password or not allowing dictionary words. But if you have one very good passphrase you use to access your password manager then you can use random strings of characters for all your passwords you do not need to remember, and only use passphrases when you need strong memorable passwords.
