PassGPT

PassGPT — the GPT-2-based language model trained on millions of leaked passwords. Instead of guessing from a wordlist, it writes passwords one character at a time the way a human would, and its guided generation mode can produce passwords matching arbitrary constraints. It cracked twice as many unseen passwords as the GAN-based methods before it. Research by Javier Rando, Fernando Perez-Cruz and Briland Hitaj, ESORICS 2023.
