Basic Information
As an account administrator, both you and your IAM users can manage basic information on this page.
![](https://support.huaweicloud.com/intl/en-us/my-kualalumpur-1-usermanual-iam/public_sys-resources/note_3.0-en-us.png)
- A mobile number or an email address can be bound only to one account or IAM user.
- Only one mobile number, email address, and virtual MFA device can be bound to an account or IAM user.
Changing the Login Password, Mobile Number, or Email Address
The methods for changing the login password, mobile number, virtual MFA device, and email address are similar. To change the login password, do as follows:
- Go to the Security Settings page.
- Click the Basic Information tab, and click Change in the Login Password row.
- (Optional) Select email address or mobile number verification, and enter the verification code.
If neither email address nor mobile number is bound, no verification is required.
- Enter the old password and new password, and enter the new password again.
- The password cannot be the username or the username spelled backwards. For example, if the username is A12345, the password cannot be A12345, a12345, 54321A, or 54321a.
- To prevent password cracking, the administrator can configure the password policy to define password requirements, such as minimum password length. For details, see Password Policy.
- Click OK.
