Password generator
Length and charset beat memorable phrases
Sixteen random characters from four pools beat an eight-letter dictionary word with a digit suffix. Slider runs 8 to 64. Toggle pools to match site rules (some banks disallow symbols).
Click Generate for a new string. Copy writes to clipboard with a two-second confirmation label.
At least one charset must stay on or the tool refuses to run.
After generate: store and encode safely
Paste into a password manager, not a Slack thread. For API keys you must transmit once, pair with the Base64 Encoder / Decoder only if the receiving system expects encoding, not for security.
QR codes for Wi-Fi join strings can be built in the QR Code Generator after you compose the password offline.
Inspect JWT secrets length requirements with the JWT Decoder on a test token, not on production secrets in chat.
Regenerate on policy change, not on every login
One password per site. Regenerate when a vendor reports a breach or when your policy adds symbol requirements.
Uncheck ambiguous characters (0/O, 1/l) manually by regenerating until the string looks clean if a legacy app rejects them.
This page does not check Have I Been Pwned. Your manager should.
Frequently Asked Questions (FAQ)
How random are the passwords?
Each character is picked with crypto.getRandomValues from the selected charset. Length 8 to 64 via slider. Default 16 with all four charsets enabled.
What if no charset is checked?
Generate is blocked with an alert: select at least one of uppercase, lowercase, numbers, or symbols. Copy stays disabled until a valid password exists.
Are these passwords stored or logged?
No. Generation is client-side only. Copy goes to your clipboard. Close the tab and the string is gone unless you saved it in a password manager.
Which symbols are included?
Default symbol set: ! @ # $ % ^ & * ( ) - _ = + [ ] { }. Uncheck symbols for systems that reject punctuation.
Can I exclude similar characters like 0 and O?
Not as a separate toggle. Uncheck a charset to drop it entirely (for example turn off numbers if you want no 0). Length is 8 to 64. Generation uses crypto.getRandomValues, not Math.random. Nothing is stored or logged on a server.
