Argon2id Generator - Modern Password Hashing Winner
Generate Argon2id hashes - the modern memory-hard password hashing standard resistant to GPU cracking.
About
Argon2id is the recommended variant of Argon2, the winner of the Password Hashing Competition (2015), combining data-independent and data-dependent memory access to resist hardware attacks while balancing side-channel resistance and brute-force cost.

Frequently Asked Questions
OWASP recommends: m=19 MiB (memory), t=2 (iterations), p=1 (parallelism) as a minimum. For higher security, use m=46 MiB with t=1. Adjust based on your server's available memory and acceptable login delay (typically 0.5-1 second).
Argon2d uses data-dependent memory access (best GPU resistance, vulnerable to side channels). Argon2i uses data-independent access (side-channel resistant, lower GPU resistance). Argon2id is the recommended hybrid: first half data-dependent, second half independent.
Argon2id is designed for password hashing, not mining. For mining, Argon2d is preferred because its data-dependent memory access provides maximum resistance to GPUs. However, most cryptocurrencies use specialized algorithms (like Scrypt, Ethash, or SHA-256d) designed specifically for mining.
