Initialize User Password ​

If you forget the user password stored in the local database, it cannot be retrieved as it is encrypted using bcrypt. However, you can reset it by creating a default user account and then updating the password to your preference.

Steps to Reset the Password ​

1. Stop the Dashboard Service ​

To ensure data consistency and prevent conflicts, it is recommended to stop the Dashboard before modifying the database.

2. Locate the Database File ​

The database file is typically located at:

plaintext
/opt/nezha/dashboard/data/sqlite.db

3. Query and Reset the User Table ​

Use the SQLite command-line tool to interact with the database:

  1. Query Existing Users: Run the following command to list all existing users:

    bash
    sqlite3 /opt/nezha/dashboard/data/sqlite.db "SELECT * FROM users;"

  2. Clear the User Table: If you need to reset the user table, run the following command to delete all user records:

    bash
    sqlite3 /opt/nezha/dashboard/data/sqlite.db "DELETE FROM users;"

4. Restart the Dashboard ​

After modifying the database, restart the Dashboard to apply changes.

5. Login Using the Default Account ​

During initialization, the Dashboard checks if the user table is empty. If it is, a default user account is created automatically.
You can log in with the following credentials:

  • Username: admin
  • Password: admin

Post-Reset Actions ​

Once logged in, it is strongly recommended to change the default password immediately for security reasons:

  1. Go to Profile → Personal Info.
  2. Select Update Profile.
  3. Set a new, secure password.

Important Notes ​

  • Backup Before Modifying: Always create a backup of the database before making any changes:
    bash
    cp /opt/nezha/dashboard/data/sqlite.db /opt/nezha/dashboard/data/sqlite.db.bak
  • Caution: Clearing the user table will remove all existing user accounts, including administrators. Proceed only if you are certain about the operation.
