Frequently asked questions
How secure are these passwords?
They're generated with the browser's Web Crypto API, the same secure source used by banking and authentication libraries.
Are generated passwords saved anywhere?
No. Nothing leaves your browser. Once you close the tab, the passwords are gone — copy them to a password manager first.
What length should I choose?
16+ characters with mixed types is excellent for most accounts. For high-value accounts (email, banking) use 24+.
Should I include symbols?
Yes when the site allows them — symbols dramatically increase entropy. Some legacy systems reject certain symbols, so check first.
Can I generate memorable passphrases instead?
This generator focuses on random strings. For passphrases, use 4–6 random dictionary words separated by hyphens.
How often should I change my passwords?
Modern guidance (NIST 800-63B) says only change them after a known breach. A long unique password in a manager is safer than rotation.
What does password entropy mean?
Entropy measures unpredictability in bits. 80+ bits is strong; 100+ bits is overkill for almost any threat. A 16-char random mix gives ~95 bits.
Is it safe to generate passwords in a browser?
Yes — Web Crypto runs in the same sandbox as your password manager and uses the OS-level secure RNG. Far safer than typing your own.
Should I use the same password for similar sites?
Never. Reusing passwords means one breach compromises every account. Use a password manager and a unique password per site.
What's a good password manager to store these in?
Bitwarden (free, open source), 1Password, and Apple/Google Passwords are all solid. Pick one and never type a password again.
Why does the strength meter say my password is weak?
Strength considers length, character variety, and dictionary patterns. Even 'P@ssw0rd!' is weak; 16+ random chars from all sets is strong.
Can I generate PIN codes or numeric-only passwords?
Yes — uncheck letters and symbols, leave only numbers, and set the length you need (typically 4–8 for PINs).
Are these passwords compliant with corporate policies?
Most policies require length, mixed case, numbers, and symbols. Toggle all four sets and set length to your policy minimum.
Can I generate a password that excludes ambiguous characters?
Yes — enable the 'exclude similar' option to skip characters like 0/O and 1/l/I, useful for passwords you'll type by hand.
Will I ever need to type these passwords?
Ideally never — your password manager autofills them. If you do, increase length comfort using passphrases instead of random strings.
