When running PostgreSQL inside a docker container (e.g. DigitalOcean / AWS official image), follow these steps:

1. Use a tool like https://bcrypt-generator.com/ to generate a bcrypt hash of the password you want. The number of rounds must be **12**.
1. Use a tool like https://bcrypt-generator.com/ to generate a bcrypt hash of the password you want. The number of rounds must be **12**. Note that, in the command below, every dollar sign ($) in your hashed password has to be *escaped* by a single backslash (\\), otherwise your password won't get recognized properly.
2. Connect to your machine / droplet via SSH.
3. Run the following command, replacing `HASH-PASSWORD` with the hash generated in step 1 and `YOUR-EMAIL` with the email address of the account you want to reset:
3. Run the following command, replacing `CONTAINER` with the name of the docker container running your database, `USERNAME` with the username used for your database, `DATABASE` with the name of your database, `HASH-PASSWORD` with the hash generated in step 1 and `YOUR-EMAIL` with the email address of the account you want to reset:

```bash
docker exec db psql -U wiki -d wiki -c "UPDATE users SET password = 'HASH-PASSWORD' WHERE email = 'YOUR-EMAIL';"
docker exec CONTAINER psql -U USERNAME -d DATABASE -c "UPDATE users SET password = 'HASH-PASSWORD' WHERE email = 'YOUR-EMAIL';"
```

#### Forgot user email
If you forgot which email you used for logging in, run the following command to list all users' emails and passwords:

```bash
docker exec CONTAINER psql -U USERNAME -d DATABASE -c "SELECT email, password FROM users;"
```

#### Username and password of the database
If you forgot your username/password for your database, try looking at the environment variables of your docker container by running

```bash
docker exec CONTAINER printenv
```

You're looking for the variables called `POSTGRES_PASSWORD`, `POSTGRES_USER` and `POSTGRES_DB`. Use them in their respective places in the command above.
