FAQ
What makes a good master password?
A good master password is at least 16 characters (20 recommended), uses all character types, and is completely random. Alternatively, a 4-5 word random passphrase works well since you need to memorize it.
Should I memorize or write down my master password?
You must memorize it for daily use. Additionally, write it on paper and store it in a secure physical location (like a safe) in case you forget it. Never store it digitally outside your password manager.
How often should I change my master password?
Only change it if you suspect it has been compromised. Frequent changes increase the risk of forgetting it. A strong, unique master password does not need regular rotation.
