Argon2id FAQ
What is Argon2id?
Argon2id is the recommended variant of the Argon2 password hashing algorithm. It won the 2015 Password Hashing Competition and combines resistance to both side-channel and GPU-based attacks.
What parameters should I use?
OWASP recommends: memory ≥ 46 MiB (47104 KB), iterations = 1, parallelism = 1 as a first config. Alternatively: memory ≥ 19 MiB, iterations = 2, parallelism = 1. Target ~1 second per hash.
Why is Argon2id recommended?
Argon2id is the OWASP and IETF recommended choice for password hashing. It provides the best balance of resistance against side-channel attacks (from Argon2i) and GPU cracking (from Argon2d).
How does memory cost help?
Higher memory requirements make GPU/ASIC attacks impractical because attackers must provision expensive memory for each parallel hash attempt, unlike fast hashes that use minimal memory.
