Step 2: Log on to ossbrowser

You can use an AccessKey pair or authorization token to log on to ossbrowser. A proxy may cause a logon attempt to fail. We recommend that you do not log on by using a proxy.

Note

Log on to ossbrowser by using an AccessKey pair: Applicable to scenarios where long-term access to resources in a bucket is required. You can use the AccessKey pair of an Alibaba Cloud account or a RAM user to log on to ossbrowser. For more information about how to create an AccessKey pair, see Create an AccessKey pair.
Log on to ossbrowser by using temporary access credentials obtained from STS: Applicable to granting temporary access to resources in a bucket to other users. You can use Security Token Service (STS) to generate temporary access credentials for users to log on to ossbrowser and access your OSS resources within a specific period of time. For more information about how to create an AccessKey pair, see Use temporary access credentials provided by STS to access OSS.
Log on to ossbrowser by using an authorization token: Applicable to granting temporary access to a directory in a bucket for other users. You can Create an AccessKey pair and provide it to other authorized users for temporary access to a directory in your bucket. The temporary authorization token automatically becomes invalid after it expires.

Log on to ossbrowser by using an AccessKey pair

The following table describes the parameters that you can configure when you log on to ossbrowser by using an AccessKey pair.

Parameter	Description
Endpoint	The endpoint of the region in which the bucket that you want to access is located. Default (Public Cloud): The default endpoint of the region in which the bucket that you want to access is located is used to log on to ossbrowser. If you select this value, you can select HTTPS encryption to encrypt data in transit. Important For regions that do not support this access method, you can select Customize for Endpoint. Customize: The specified endpoint is used to log on to ossbrowser. Example: `http(s)://oss-cn-wulanchabu.aliyuncs.com`. If you select this value, you can specify any OSS endpoint for the public cloud. For more information about regions and their endpoints, see Regions, endpoints and open ports. Note If you do not use an internal endpoint, Internet traffic is generated. You are charged for the generated traffic. For more information, see Traffic fees. cname: A custom domain name is used to access OSS resources. You must map a custom domain name to the bucket that you want to access in advance. For more information, see Map custom domain names. After you map a custom domain name to the bucket, you can use the custom domain name to access the bucket.
AccessKeyId and AccessKeySecret	The AccessKey pair of your account. For information about how to obtain an AccessKey pair, see Obtain an AccessKey pair. Important To ensure data security, we recommend that you log on to ossbrowser by using the AccessKey pair of a RAM user. To use the AccessKey pair of a RAM user to log on to ossbrowser, make sure that the following policies are attached to the RAM user: `AliyunOSSFullAccess`, `AliyunRAMFullAccess`, and `AliyunSTSAssumeRoleAccess`. For more information, see Manage permissions.
Preset OSS Path	If the current account has permissions to access only a specific bucket or a specific path in a bucket, you must specify this parameter. Format: oss://bucketname/path For example, if you are authorized to access only objects and subdirectories in the examplefolder directory of a bucket named examplebucket, enter `oss://examplebucket/examplefolder/`. If pay-by-requester is enabled for the bucket that you are authorized to access and you are not the bucket owner, select request payer. Otherwise, the `AccessDenied` error code is returned when you access the resources in the preset path. If you select request payer, you are charged based on the traffic and the number of requests that are generated when you access the resources in the path specified by Preset OSS Path. For more information about the pay-by-requester feature, see Enable pay-by-requester.
Region	If you select Default (Public Cloud) for Endpoint, you must specify the region of the bucket in which the resources in the path specified by Preset OSS Path are stored.
Keep me logged in	If you select this option, you are automatically logged on the next time you start ossbrowser.
Remember	If you select this option, your AccessKey pair used to log on to ossbrowser is remembered. The next time you log on to ossbrowser, click AK Histories and select the remembered AccessKey pair instead of reentering the AccessKey pair. Warning For security reasons, do not select this option if you use a shared computer.

Log on to ossbrowser by using temporary access credentials obtained from STS

The following table describes the parameters that you can configure when you log on to ossbrowser by using temporary access credentials obtained from STS.

Parameter	Description
Endpoint	The endpoint of the region in which the bucket that you want to access is located. Default (Public Cloud): The default endpoint of the region in which the bucket that you want to access is located is used to log on to ossbrowser. If you select this value, you can select HTTPS encryption to encrypt data in transit. Important For regions that do not support this access method, you can select Customize for Endpoint. Customize: The specified endpoint is used to log on to ossbrowser. Example: `http(s)://oss-cn-wulanchabu.aliyuncs.com`. If you select this value, you can specify any OSS endpoint for the public cloud. For more information about regions and their endpoints, see Regions, endpoints and open ports. Note If you do not use an internal endpoint, Internet traffic is generated. You are charged for the generated traffic. For more information, see Traffic fees. cname: A custom domain name is used to access OSS resources. You must map a custom domain name to the bucket that you want to access in advance. For more information, see Map custom domain names. After you map a custom domain name to the bucket, you can use the custom domain name to access the bucket.
AccessKeyId, AccessKeySecret, and STS Token	The temporary access credentials obtained from STS. The temporary access credentials consist of an AccessKey pair and an STS token. For more information, see Step 5: Use the RAM user to assume the RAM role to obtain temporary access credentials. Note An STS Token is required only when the AccessKeyId is in the `STS.XXX` format.
Preset OSS Path	If the current account has permissions to access only a specific bucket or a specific path in a bucket, you must specify this parameter. Format: oss://bucketname/path For example, if you are authorized to access only objects and subdirectories in the examplefolder directory of a bucket named examplebucket, enter `oss://examplebucket/examplefolder/`. If pay-by-requester is enabled for the bucket that you are authorized to access and you are not the bucket owner, select request payer. Otherwise, the `AccessDenied` error code is returned when you access the resources in the preset path. If you select request payer, you are charged based on the traffic and the number of requests that are generated when you access the resources in the path specified by Preset OSS Path. For more information about the pay-by-requester feature, see Enable pay-by-requester.
Region	If you select Default (Public Cloud) for Endpoint, you must specify the region of the bucket in which the resources in the path specified by Preset OSS Path are stored.
Keep me logged in	If you select this option, you are automatically logged on the next time you start ossbrowser.
Remember	If you select this option, your AccessKey pair used to log on to ossbrowser is remembered. The next time you log on to ossbrowser, click AK Histories and select the remembered AccessKey pair instead of reentering the AccessKey pair. Warning For security reasons, do not select this option if you use a shared computer.
