Some people don't have PINs. Some do have PINs but don't know it. Others simply can't remember their PINs. Your PIN helps the University restrict Stanford-only services to those who should have them, as required by law. Students are given PINs when they first enroll at Stanford.
Some faculty never get a PIN because they've simply never needed one.
Because your PIN is secret, and is known only by you, it provides a check each time you access a computer service like Leland's Open Program. Never reveal your PIN to anyone.
