Where MySQL stores your login credentials

Your MySQL username and password are stored in your hosting account's control panel, not on your computer. The exact location depends on your hosting provider, but most use cPanel, Plesk, or a custom dashboard. You will not find them in a file on your hard drive — they live on the server where your database runs.

If you set up MySQL yourself on your own computer or server, the credentials are in whatever configuration file you created during installation. On Windows, this might be in the MySQL installation folder. On Linux, it is typically in /etc/mysql/ or a similar system directory. On macOS with a package manager like Homebrew, check the installation location you chose.

The most common scenario is that you are renting hosting from a provider like GoDaddy, Bluehost, HostGator, or Dreamhost. In that case, your control panel is where you look first.

Key Takeaways

  • Hosted MySQL credentials are in your hosting provider's control panel under a section called Database, MySQL, or similar — not in a file on your computer.
  • cPanel shows your MySQL username and password in the MySQL Databases tool, and you can reset the password there if you forget it.
  • Plesk stores database credentials in the Databases section, and you can view or change them without contacting support.
  • If you installed MySQL yourself, check the configuration file in your MySQL installation directory or the notes you saved during setup.
  • Most hosting providers let you reset a forgotten password through the control panel without losing your data.

Finding credentials in cPanel

Log into your cPanel account (usually at yourdomain.com:2083 or through your hosting provider's login page). Look for a section called Databases, MySQL Databases, or Database. Click it.

You will see a list of databases you have created. Next to each one, cPanel shows the username associated with that database. The password is not displayed for security reasons, but you can reset it by clicking the database name or a "Change Password" button. Write down the username exactly as it appears — usernames are case-sensitive in some contexts, and you need the exact spelling.

If you need to create a new database user with a password you choose, cPanel has an option to add a new user in the same MySQL Databases section. You set the username and password there, then assign that user to your database.

Finding credentials in Plesk

Log into your Plesk control panel (usually at yourdomain.com:8443 or through your hosting provider's login page). Click Databases in the left menu.

You will see your databases listed. Click the database name to open its details. The username appears in the database information. Like cPanel, Plesk does not display the password, but you can reset it by clicking Change Password or a similar option. Some versions of Plesk show a Users tab where you can see all users assigned to that database and manage their passwords.

If you need to add a new database user, Plesk has an option in the Databases section to create one. You set the username and password, then assign permissions to your database.

Resetting a forgotten password

If you do not remember your MySQL password, you do not need to contact support. Both cPanel and Plesk let you reset it yourself through the control panel without affecting your data. Log in, find your database in the MySQL or Databases section, and look for a password reset or change password option. Set a new password and save it somewhere safe.

If you installed MySQL on your own server and forgot the root password, the process is more involved. On Linux, you can restart MySQL in safe mode and reset the root password from the command line. On Windows, you may need to reinstall MySQL or use a password recovery tool. Search for "reset MySQL root password [your operating system]" to find the exact steps for your setup.

Finding credentials in custom hosting dashboards

Some smaller hosting providers use their own dashboard instead of cPanel or Plesk. Log into your hosting account and look for a section labeled Databases, MySQL, Database Management, or Tools. The layout varies, but the information is always there — username, database name, and an option to reset the password.

If you cannot find it, check your hosting provider's help documentation or contact their support team. They can point you to the exact page and show you how to view or reset your credentials. Most providers respond within a few hours.

Storing credentials safely

Once you have your username and password, write them down in a password manager like Bitwarden, 1Password, or KeePass. Do not store them in a plain text file on your desktop or email them to yourself. A password manager encrypts them and lets you retrieve them securely whenever you need them.

If you are setting up a new database, choose a strong password — at least 12 characters with uppercase, lowercase, numbers, and symbols. Avoid dictionary words or personal information. Your hosting provider's control panel usually has a password generator you can use.

Connecting to MySQL with your credentials

Once you have your username and password, you use them to connect to your database from your process or a database client. In a web process, you typically put them in a configuration file like wp-config.php (WordPress), config.php (custom PHP), or .env (Laravel, Node.js). The format depends on your process, but it always looks something like this: username goes in one field, password in another, database name in a third.

If you are connecting from a desktop tool like MySQL Workbench or phpMyAdmin, you enter the username, password, and hostname (usually localhost if it is on the same server, or your hosting provider's database server address). The tool will test the connection and let you know if the credentials are correct.

Frequently Asked Questions

Can I see my MySQL password in the control panel?

No. cPanel and Plesk hide passwords for security — they only show the username. You can reset the password to a new one you choose, but you cannot view the old one. If you need the password, reset it to something you will remember or generate a new one.

What is the difference between the database name and the username?

The database name is the container where your data lives. The username is the account that accesses it. One user can access multiple databases, and one database can have multiple users with different permission levels. You need both to connect.

Where do I find the hostname for my MySQL connection?

For hosted MySQL, the hostname is usually localhost if your website and database are on the same server. Some hosting providers use a different hostname like mysql.yourdomain.com or an IP address. Check your hosting provider's documentation or the database details page in your control panel.

Can I change my MySQL username?

Yes, but it is usually easier to create a new user and delete the old one. In cPanel or Plesk, add a new database user with the username you want, assign it to your database, update your process to use the new credentials, then delete the old user. This avoids downtime.

What if my hosting provider does not have cPanel or Plesk?

Look for a Databases, MySQL, or Database Management section in your hosting account dashboard. If you cannot find it, check the provider's help documentation or contact their support team. They can show you where to view and reset your credentials.
