As of May 2023, OWASP's Password Storage Cheat Sheet recommends that people "use Argon2id with a minimum configuration of 19 MiB of memory, an iteration count of 2, and 1 degree of parallelism."[10]

OWASP recommends that Argon2id should be preferred over Argon2d and Argon2i because it provides a balanced resistance to both GPU-based attacks and side-channel attacks.[10]

OWASP further notes that the following Argon2id options provide equivalent cryptographic strength and simply trade off memory usage for compute workload:[10]

Memory: 46 MiB, Iterations: 1, Parallelism: 1
Memory: 19 MiB, Iterations: 2, Parallelism: 1
Memory: 12 MiB, Iterations: 3, Parallelism: 1
Memory: 9 MiB, Iterations: 4, Parallelism: 1
Memory: 7 MiB, Iterations: 5, Parallelism: 1
