5-Word Passphrase Generator
A 5-word passphrase generator creates passphrases with ~55 bits of entropy — above the threshold for strong security on virtually all online accounts. Five words provide the extra security margin recommended for email, banking, and any account containing sensitive data, while remaining memorable.
Why upgrade to 5 words?
Upgrading from 4 to 5 words adds approximately 11 bits of entropy, multiplying the search space by 2,000. A 5-word passphrase from a 2,000-word list has ~55 bits of entropy — solidly in the "strong" category for online accounts. This is especially important for accounts that can be used to reset other accounts (email, phone), which deserve additional security margin.
5-word passphrases for important accounts
We recommend 5-word passphrases for: primary email accounts, banking and financial accounts, social media accounts with large followings or linked payment methods, and accounts used for "Sign in with Google/Facebook". These accounts have outsized impact if compromised — the additional word's security margin is worth the slight memorability cost.
