Randomify Tool
Random Password Generator
Choose length and character sets (upper, lower, digits, symbols) to craft strong pseudo-random strings.
How to Use the Random Password Generator
- 1Set the password length using the slider (4–64 characters) or click a quick preset like 12, 16, 24, or 32.
- 2Choose which character types to include: lowercase letters, uppercase letters, digits, and symbols. At least one type must be selected.
- 3Toggle "Exclude similar characters" if the password will be typed manually — this removes confusing pairs like 0/O and 1/l/I.
- 4Click Generate. The password appears in a monospace display with a strength meter showing Weak, Fair, Strong, or Very Strong.
- 5Click Copy to place the password on your clipboard. The entropy in bits is displayed below the meter for technical reference.
When to Use the Random Password Generator
A new employee setting up multiple work accounts generates a different strong password for each service, using 16+ characters with all four character types. Each password scores "Very Strong" on the entropy meter before they paste it into their password manager.
A developer provisioning test accounts needs quick throwaway credentials. The quick-preset buttons make it easy to churn out 12-character passwords without adjusting the slider every time.
A parent helping their child create a first email account uses the "Exclude similar characters" toggle so the password is easy to type without confusing O with 0 or l with 1.
A security-conscious freelancer generates a 32-character passphrase for an encryption key, checks that the entropy is above 128 bits, and copies it into their vault.
Random Password Generator vs. Random Number Generator
The Password Generator creates character strings optimised for authentication security, with controls for character types, exclusions, and a strength meter. The Random Number Generator produces integers in a numeric range. If you need a login credential, use the Password Generator. If you need a PIN, raffle number, or test integer, the Number Generator is the right tool. Try the Random Number Generator →
Pick a length between 4 and 64 characters, then toggle lowercase, uppercase, digits, and symbols to match company policies or app requirements. Randomify assembles a custom character pool and produces a fresh string entirely in your browser, so test credentials or throwaway logins never touch a server. The neon display is easy to read on dark themes, and the one-click copy button drops the password wherever you need it.
For best practices, aim for 12+ characters with at least three character sets, then store sensitive outputs in a trusted password manager. This tool shines for quick prototypes, QA environments, creative writing prompts, or anytime you need unique strings on demand.
- •Create strong passwords for new accounts quickly.
- •Generate temporary passwords for test environments.
- •Exclude ambiguous characters for easier manual typing.
- •Use at least 12 characters with multiple character sets for best entropy.
- •Store sensitive passwords in a dedicated password manager.
