Argon2 Hash Generator
Configure and generate next-generation Argon2id, Argon2i, and Argon2d memory-hard password hashes.
1 How to Use the Argon2 Hash Generator
Select Argon2 variant: Argon2id (recommended hybrid), Argon2i, or Argon2d.
Enter password text and customize memory cost (KiB), time iterations, and parallelism threads.
Generate the standardized PHC string: $argon2id$v=19$m=...,t=...,p=...$hash.
Copy the resulting string for your backend implementation (PHP, Node.js, Go, Python).

4 Frequently Asked Questions
Q. Why is Argon2id the modern gold standard?
Argon2id won the Password Hashing Competition because it provides both side-channel attack resistance and high memory-hardness to defeat GPU/ASIC attacks.
Q. What is the difference between Argon2i, Argon2d, and Argon2id?
Argon2d is optimized for resistance against GPU cracking, Argon2i defends against side-channel timing attacks, and Argon2id combines both for optimal real-world security.
