Generate strong passwords and passphrases, inspect otpauth URIs, and preview TOTP codes locally.
Generate credentials and debug TOTP locally.
Generate random passwords with configurable character sets and length.
Create readable hyphenated passphrases for temporary credentials.
Paste an otpauth URI or base32 secret and view the current code.
Pairs well with the QR tool for otpauth URI generation and decoding.
Copy credentials or codes quickly while keeping them local.
Generation and TOTP calculation happen in the browser.
Use test secrets whenever possible. The tool runs locally, but production secrets should still be handled carefully.
The estimate uses character pool size and password length to calculate approximate entropy bits.
No. They live only in the current page until you copy or regenerate them.
