Hello,
If you forget or want to change the web login password, log in to the switch through the console port, Telnet, or STelnet and set a new password after login.
NOTICE: The Telnet protocol has security vulnerabilities. It is recommended that you log in to the device through the console port or using STelnet V2.
# Set the user name and password to admin123 and Huawei@123 respectively.
