https://github.com/erlang/otp/security/advisories/GHSA-3w6p-vwhf-wvp4 reports:

A timing-based username enumeration vulnerability during password authentication with the user_passwords option has been fixed by performing a dummy PBKDF2 computation for invalid usernames, so authentication timing no longer reveals whether a username exists.
