Password and passphrase basics
A password is often thought of as a relatively compact string of characters, while a passphrase usually combines several words into a longer credential. Either can be secure when it is long, unique, and sufficiently unpredictable.
Length and randomness
Length helps, but a long phrase made from an obvious quotation or familiar saying may still be predictable. Likewise, a shorter random password may have a large search space but can be difficult to remember without a password manager.
Memorability
Passphrases can be useful when you must type and remember a credential yourself. Randomly selected words are generally preferable to famous phrases, personal sentences, song lyrics, or predictable word combinations.
When random passwords are better
Random generated passwords are especially practical when a password manager will store and autofill them. In that situation, memorability is less important, so you can prioritize length and randomness.
When a passphrase can make sense
The right choice depends on the account and how you will store the credential. Whichever format you choose, do not reuse it across accounts.

Generate a Strong Password →Frequently Asked Questions
Should I use the same password on more than one account?
No. A unique password for every account limits the damage if one service is breached.
Should I save generated passwords?
Yes. Save the final credential in a trusted password manager before leaving or refreshing the generator.
Does a strong password replace MFA?
No. Enable multi-factor authentication when it is available.
