Password Generator builds a random password, a word passphrase, or a pronounceable password in the browser with crypto.getRandomValues. It shows a strength meter, entropy in bits, and offline crack-time estimates. The password is not uploaded.
Generate random passwords, word passphrases, or pronounceable memorable passwords in your browser. See a strength meter, entropy in bits, and offline crack-time estimates. Uses crypto.getRandomValues; nothing is uploaded.
Each extra bit doubles the search space. Two more characters from a 70-symbol alphabet add about 12 bits, because 2 × log2(70) is about 12.3. Length usually beats a complexity rule that keeps the password short.
No. Generation runs locally in your browser using crypto.getRandomValues for cryptographically strong randomness. Nothing is uploaded or logged by Roy's Tools.
Entropy is how unpredictable a password is, measured in bits. Each bit doubles the search space, so 80 bits means roughly 2^80 possible passwords. 80+ bits is a comfortable target for most personal accounts.
We show four offline fast-hash estimates—from a single RTX 5090 through hypothetical future state-scale hardware—and report the average time to search half the keyspace. Online attacks against a real service are typically far slower.
Both can be equally strong. Passphrases are easier to remember and type; random character passwords are shorter for the same entropy. Pick whichever you'll actually use without reusing.
Usually yes. Adding two more random characters from a 70-symbol alphabet adds about 12 bits of entropy, which beats most complexity-rule tweaks. Aim for length first, complexity second.
