LeTourneau systems require passwords long enough to meet current government security recommendations. Security experts recommend that you choose a passphrase instead of one very long password to help you use a longer password without the difficulty of remembering a very long traditional password.
What are passphrases?
Passphrases are longer, memorable phrases that you can remember, but are unusual enough that only you are likely to think of them.
For instance: "riding a horse on the carpet" is a great passphrase. It doesn't make a lot of sense, but isn't hard to remember. Note that there are no capital letters or numbers. You can add those if you want, but if your phrase is sufficiently random and long, they don't add to the security of your passphrase. Spaces are optional, use them if you want!
"For God so loved the world" is not quite as good a passphrase because at a Christian University it might be an expected phrase you would use, nonetheless either is better than a password like "Letmein2023"
Passphrases at LETU cannot contain words found in commonly compromised passwords.
