Issue Description
When you try to connect to a TencentDB for MySQL instance, the system prompts ERROR 1045 (28000): Access denied for user 'XXX'@'XXX'.
﻿
Common Causes
1. The username is incorrect.
2. The host name is incorrect.
3. The password is incorrect.
Solutions
Check whether the username, host, and password are correct.
Troubleshooting
1. Log in to the TencentDB for MySQL console and click the ID of the target instance in the instance list to enter the instance management page.
2. On the instance management page, select Database Management > Account Management and check whether the account name and host name match.
Note: 
If the account name and host name do not match, you can proceed as follows:
Method 1: check whether the host has another account name, and if so, use that account name and the corresponding password for login.
Method 2: add the IP address of the current host under the current account name. To clone the account, click Clone Account in the Operation column of the account, change the Host parameter value to the IP address of the host you need to log in to in the Clone Account pop-up window, and click OK.

3. Try again and make sure that the entered password is correct. If you forgot the password, you can find the account for which to reset the password and select More > Reset Password.
