June 30, 2022
In June 2022, IAM had an issue that resulted in excess usage metrics for service accounts and service account keys when any of the following actions were performed:
- Listing service account keys
- Getting a service account key
- Disabling a service account key
- Enabling a service account key
Each time you took any of these actions, Cloud Monitoring recorded an authentication usage metric for the parent service account, and for each of its service account keys, regardless of whether you used the service account or its keys to authenticate. These excess metrics were visible in Cloud Monitoring, and in the metrics for individual service accounts and keys, from June 7, 2022, through June 17, 2022.
In addition, these excess metrics were visible in other systems that use data from Cloud Monitoring, including Activity Analyzer, which shows when service accounts and keys were used to authenticate, and service account insights, which provide findings about unused service accounts. Excess metrics were visible in these systems from June 7, 2022, through June 22, 2022.
This issue has been corrected, and Cloud Monitoring is no longer recording these excess metrics. However, the last authentication time for each service account and key will continue to reflect the excess metrics indefinitely, until you authenticate with the service account or key again.
May 05, 2022
Documentation for Activity Analyzer, IAM insights, IAM Policy Troubleshooter, IAM role recommendations, and IAM Policy Simulator has moved to the Policy Intelligence documentation.

If you run one of the gcloud tool's add-iam-policy-binding commands, and the IAM policy contains conditional role bindings for that role, the gcloud tool prompts you to choose one of the condition expressions that exists in the policy. If you choose a condition expression that contains a comma, the command fails.
To work around this issue, use the --condition flag to specify a condition expression on the command line.

If a role binding in an IAM policy refers to a deleted member (for example, deleted:user:tamika@example.com?uid=123456789012345678901), you can now add role bindings for a newly created member with the same name (in this case, user:tamika@example.com). The role bindings always apply to the newly created member.
For details, see the documentation for policies with deleted members.

July 20, 2020
We are delaying the upcoming changes for deleted members that are bound to a role. These changes will take effect starting on August 31, 2020.
July 01, 2020
The organization policy constraint to prevent automatic role grants to IAM service accounts is now generally available. To improve security, we strongly recommend that you enable this constraint.
Starting on July 27, 2020, IAM policies will identify deleted members that are bound to a role. Deleted members have the prefix deleted: and the suffix ?uid=numeric-id.
For example, if you delete the account for the user tamika@example.com, and a policy binds that user to a role, the policy shows an identifier similar to deleted:user:tamika@example.com?uid=123456789012345678901.
For SetIamPolicy requests, you can use this new syntax starting on July 27. For GetIamPolicy and SetIamPolicy responses, you might see the new prefix and suffix in some, but not all, responses until we finish rolling out the change. We expect to complete the rollout by July 31, 2020.
See the documentation for a detailed example, as well as guidance on updating policies that contain deleted members.
Starting on July 27, 2020, if a binding in a policy refers to a deleted member (for example, deleted:user:tamika@example.com?uid=123456789012345678901), you cannot add a binding for a newly created member with the same name (in this case, user:tamika@example.com). If you try to add a binding for the newly created member, IAM will apply the binding to the deleted member instead.
To resolve this issue, see our guidance on updating policies that contain deleted members.
June 22, 2020
Using the IAM API to sign JSON Web Tokens (JWTs) or binary blobs is now deprecated.
- If you use the IAM API or its client libraries to sign JWTs or binary blobs, you must migrate to the Service Account Credentials API before July 1, 2021.
- If you use the
gcloudcommand-line tool to sign JWTs, you must prepare for changes to thegcloudtool before July 1, 2021.

February 28, 2020
IAM Conditions are now generally available. You can use IAM Conditions to define and enforce conditional, attribute-based access control for Google Cloud resources.
For IAM Conditions, you can now use the extract() function to extract a value from a resource name. This function enables condition expressions to refer to an arbitrary part of the resource name.
February 21, 2020
A version 1 IAM policy can now include conditional role bindings. The role name in these bindings includes the string withcond, followed by a hash value. For example: roles/iam.serviceAccountAdmin_withcond_2b17cc25d2cd9e2c54d8
If you see the string withcond in an IAM policy, follow the steps in the troubleshooting guide.
February 18, 2020
You can now learn about IAM audit logging for service accounts and see examples of audit logs for service accounts.
February 13, 2020
The IAM recommender is now generally available. The IAM recommender helps you enforce the principle of least privilege by ensuring that members have only the permissions that they actually use.
February 04, 2020
IAM Conditions now supports forwarding rule attributes, currently in beta. You can use these attributes to specify the types of forwarding rules that a member can create.
December 17, 2019
Policy Troubleshooter is now generally available. Use Policy Troubleshooter to determine why a user has access to a resource or doesn't have permission to call an API.
December 13, 2019
On December 9, we announced that IAM policies would now identify deleted members. We have temporarily reverted this change. IAM policies no longer identify deleted members.
December 12, 2019
IAM Conditions are now available in public beta. You can use IAM Conditions to define and enforce conditional, attribute-based access control for Google Cloud resources.
December 09, 2019
IAM policies now identify deleted members that are bound to a role. Deleted members have the prefix deleted: and the suffix ?uid=[NUMERIC_ID].
For example, if you delete the account for the user bob@example.com, and a policy binds that user to a role, the policy shows an identifier similar to deleted:user:bob@example.com?uid=123456789012345678901.
For SetIamPolicy requests, you can use this new syntax starting today. For GetIamPolicy and SetIamPolicy responses, because we are still rolling out this change, you might see the new prefix and suffix in some, but not all, responses. We expect to complete the rollout by December 13, 2019.
If a binding in a policy refers to a deleted member (for example, deleted:user:bob@example.com?uid=123456789012345678901), you cannot add a binding for a newly created member with the same name (in this case, user:bob@example.com). If you try to add a binding for the newly created member, IAM will apply the binding to the deleted member instead.
September 23, 2019
