How do I log on to the OSS console as a RAM user? - Object Storage Service

This topic describes how to use the credentials of a Resource Access Management (RAM) user to log on to the Object Storage Service (OSS) console.

Background information

You can use the credentials of a RAM user to log on to the OSS console in the following scenarios:

A bucket that is created by using an Alibaba Cloud account stores internal documents of your enterprise. To share specific internal documents with your employees, you can create RAM users for your employees and grant permissions to the RAM users. The RAM users can log on to the OSS console to view these documents.
Some of your partners need to periodically view specific materials. You can store the materials in a bucket, create RAM users for the partners, and grant the RAM users the permissions to access the bucket. This way, the partners can log on to the OSS console as RAM users to periodically view the materials.

Step 1: Create a RAM user

Log on to the RAM console by using an Alibaba Cloud account or a RAM user who has administrative rights.
In the left-side navigation pane, choose Identities > Users.
On the Users page, click Create User.
In the User Account Information section of the Create User page, configure the following parameters:
- Logon Name: The logon name can be up to 64 characters in length, and can contain letters, digits, periods (.), hyphens (-), and underscores (_).
- Display Name: The display name can be up to 128 characters in length.
- Tag: Click the icon and enter a tag key and a tag value. You can add one or more tags to the RAM user. This way, you can manage the RAM user based on the tags.
Note
You can click Add User to create multiple RAM users at a time.
In the Access Mode section, select an access mode and configure the required parameters.
To ensure the security of your Alibaba Cloud account, we recommend that you select only one access mode for the RAM user. This way, the RAM user for an individual is separated from the RAM user for a program.
- Console Access
  If the RAM user represents an individual, we recommend that you select Console Access for the RAM user. This way, the RAM user can use a username and password to access Alibaba Cloud. If you select Console Access, you must configure the following parameters:
  - Set Console Password: You can select Automatically Regenerate Default Password or Reset Custom Password. If you select Reset Custom Password, you must specify a password. The password must meet the complexity requirements. For more information, see Configure a password policy for RAM users.
  - Password Reset: specifies whether the RAM user is required to reset the password upon the next logon.
  - Enable MAF: specifies whether to enable multi-factor authentication (MFA) for the RAM user. After you enable MFA, you must bind an MFA device to the RAM user or allow the RAM user to bind an MFA device. For more information, see Bind an MFA device to a RAM user.
- OpenAPI Access
  If the RAM user represents a program, we recommend that you select OpenAPI Access for the RAM user. This way, the RAM user can use an AccessKey pair to access Alibaba Cloud. If you select OpenAPI Access, the system automatically generates an AccessKey ID and AccessKey secret for the RAM user. For more information, see Obtain an AccessKey pair.
  Important
  An AccessKey secret for a RAM user is displayed only after you click Create AccessKey. You cannot query the AccessKey secret in subsequent operations. Therefore, you must back up your AccessKey secret.
Click OK.
Complete security verification as prompted.

Step 2: Grant permissions to the RAM user

In the left-side navigation pane, choose Identities > Users.
On the Users page, find the required RAM user, and click Add Permissions in the Actions column.
You can also select multiple RAM users and click Add Permissions in the lower part of the page to grant permissions to the RAM users at a time.
In the Grant Permission panel, grant permissions to the RAM user.
1. Configure the Resource Scope parameter.
  - Account: The authorization takes effect on the current Alibaba Cloud account.
  - Resource Group: The authorization takes effect on a specific resource group.
    Important
    If you select Resource Group for the Resource Scope parameter, make sure that the required cloud service supports resource groups. For more information, see Services that work with Resource Group. For more information about how to grant permissions on a resource group, see Use a resource group to grant a RAM user the permissions to manage a specific ECS instance.
2. Configure the Principal parameter.
  The principal is the RAM user to which you want to grant permissions. The current RAM user is automatically selected.
3. Attach policies to the RAM user.
  To ensure that you can use the features in the OSS console after you log on as a RAM user, attach the following policies to the RAM user as shown in the following figure: AliyunOSSFullAccess, AliyunCloudMonitorFullAccess, AliyunMNSFullAccess, and AliyunCDNFullAccess.
  If system policies cannot meet your requirements, you can configure a custom policy. For more information, see Create custom policies.
4. Click Grant permissions and click Close.

Step 3: Log on to the OSS console as the RAM user

In the left-side navigation pane of the RAM console, click Overview.
In the Basic Information section on the Overview tab, obtain the logon URL of the RAM user.
Click the logon link of the RAM user. Use the username of the RAM user and click Next. Enter the credentials of the RAM user to log on to the Alibaba Cloud Management Console.
Access OSS by using the OSS console link.
