| ## SET-PASSWORD |
| |
| ### Name |
| |
| SET PASSWORD |
| |
| ### Description |
| |
| The SET PASSWORD command can be used to modify a user's login password. If the [FOR user_identity] field does not exist, then change the current user's password |
| |
| ```sql |
| SET PASSWORD [FOR user_identity] = |
| [PASSWORD('plain password')]|['hashed password'] |
| ``` |
| |
| Note that the user_identity here must exactly match the user_identity specified when creating a user with CREATE USER, otherwise an error will be reported that the user does not exist. If user_identity is not specified, the current user is 'username'@'ip', which may not match any user_identity. Current users can be viewed through SHOW GRANTS. |
| |
| The plaintext password is input in the PASSWORD() method; when using a string directly, the encrypted password needs to be passed. |
| To modify the passwords of other users, administrator privileges are required. |
| |
| ### Example |
| |
| 1. Modify the current user's password |
| |
| ```sql |
| SET PASSWORD = PASSWORD('123456') |
| SET PASSWORD = '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' |
| ``` |
| |
| 2. Modify the specified user password |
| |
| ```sql |
| SET PASSWORD FOR 'jack'@'192.%' = PASSWORD('123456') |
| SET PASSWORD FOR 'jack'@['domain'] = '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' |
| ``` |
