Argon2 Password Hash

Generate standard encoded Argon2 password hashes in the browser from a password, salt, algorithm, iterations, memory size, and parallelism.

Argon2 Password Hash

The Argon2 password hash tool generates standard encoded Argon2 output locally in the browser from a password, salt, algorithm, iterations, memory size, and parallelism, which is useful for password-storage checks, auth integration, and backend result matching.

How do you use it?

  1. Enter the password.
  2. Enter or generate the Base64 salt and add an optional secret / pepper if needed.
  3. Set the algorithm, iterations, memory size, parallelism, and hash length.
  4. Generate the result and copy or download the encoded Argon2 hash.

Features

  • Supports Argon2id, Argon2i, and Argon2d
  • Supports random salt and optional secret / pepper
  • Outputs standard encoded Argon2 hashes with copy and download support

Why use this tool?

  • Useful for checking whether frontend and backend Argon2 parameters match
  • Helpful for password-storage testing, login integration, and security experiments
  • Saves you from writing one-off scripts just to reproduce a hash
