As passwords remain the main online authentication method, focus has shifted from naive entropy to how usability improvements can increase security. Chatterjee et al. recently introduced the first two typo-tolerant password checkers, their second being usable in practice while being able to correct up to 32% of typos, with no real security cost. We propose an alternative framework which corrects up to 57% of typos without affecting user experience, at no computational cost to the server.
