F.A.Q. - jesec/flood GitHub Wiki

You can't recover a forgotten password but if you have access to server you can:

• Edit <rundir>/db/users.db and provide a valid new hash instead of the forgotten one.
  • Databases are in plain JSON.
  • Flood hashes passwords with Argon2.
• Delete <rundir>, restart flood, and flood will prompt you to create a new user. Warning all previous accounts will be lost.

Note:

• If you followed the instructions from the Install Flood as a service (systemd) page, <rundir> will be /home/download/.local/share/flood.
• Additionally, you can use the online Argon2 Hash Generator for generating a new hash.
