So, you've set up your TP-Link router, connected all your devices, and everything seemed perfect until you realized you can't remember your username and password to access the router settings. Don't worry; this is a common issue that many people face. Here's how you can find your TP-Link router username and password:

1. Check the router manual: The default username and password are usually provided in the manual that came with your router. Look for a section titled 'Login Information' or 'Admin Credentials'.
2. Check the router label: Most TP-Link routers have a label on the back or bottom that displays the default username and password. Look for fields such as 'SSID' or 'Network Key'.
3. Access the router settings: If you've changed the default login credentials and can't remember them, you can still access the router settings by resetting the router to factory defaults. Use a paperclip to press and hold the reset button for about 10 seconds until the router restarts.
4. Use default credentials: After resetting the router, you can log in using the default username and password. These are often 'admin' for both fields or 'admin' for the username and 'password' for the password.

It's crucial to change the default username and password to secure your router from unauthorized access. Once you've logged in, navigate to the settings and update the login information to something unique and secure. Remember to keep a record of your new credentials in a safe place to avoid this issue in the future.
