# Reset user 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, for example, be done with the `bcrypt` python module or the `mkpasswd` shell utility (the latter should be preinstalled on most systems):
|
|
|
|
```
|
|
python3 -c 'import bcrypt; print(bcrypt.hashpw(b"<INSERT PASSWORD HERE>", bcrypt.gensalt(rounds=10)).decode("ascii"))' # python
|
|
mkpasswd --method=bcrypt-a -R 10 # mkpasswd
|
|
```
|
|
|
|
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.
|
|
|
|
This script bundles all needed commands so you don't have to enter everything manually every time, and also checks that the username exists before writing to the database:
|
|
```sh
|
|
#!/bin/sh
|
|
set -e
|
|
|
|
printf 'User ID: '
|
|
read -r ID
|
|
if [ "$(su postgres -c "psql invidious -c \"SELECT email FROM users WHERE email = '$ID';\"" | tail -n 2 | head -n 1)" != '(1 row)' ]; then
|
|
echo 'Error: User ID does not exist'
|
|
exit 1
|
|
fi
|
|
|
|
HASH="$(mkpasswd --method=bcrypt-a -R 10)"
|
|
su postgres -c "psql invidious -c \"UPDATE users SET password = '\"'$HASH'\"' WHERE email = '\"'$ID'\"';\""
|
|
```
