+# How to reset a user's password
+
+Resetting a user's invidious password needs you to edit the database.
+
+Firstly, generate a bcrypt-encrypted hash for the new password you want to set for the user.
+
+This can be done with the `bcrypt` python module, though there are other ways of doing the same.
+
+```
+python3 -c 'import bcrypt; print(bcrypt.hashpw(b"<INSERT PASSWORD HERE>", bcrypt.gensalt(rounds=10)).decode("ascii"))'
+```
+
+To do so, first attach to the database:
+```
+# su - postgres
+$ psql
+postgres=# \c invidious
+```
+
+Now, run the following SQL query:
+```
+UPDATE users SET password = 'HASH' WHERE email = 'USERNAME';
+```
+
+After that, the password should be reset.
