Does argon2 suffer from the same vulnerability?
Seems that bcrypt, scrypt and Argon2 are all designed to slowdown attacks on specific hardware platforms. All run relatively slow on GPUs so they all work. The blog covers how to overcome this using FPGAs, specifically for bcrypt. The same might also work against scrypt and Argon2 if configured parameters are in favor of FPGAs. If parameters exceed the specs of FPGAs, they will be slow as well. So depends on the configuration of the algorithm.
