Naming your secrets
To help ensure that {% data variables.product.prodname_dotcom %} redacts your secrets in logs correctly, avoid using structured data as the values of secrets.
The following rules apply to secret names:
{% data reusables.actions.actions-secrets-and-variables-naming %}
{% data reusables.codespaces.secret-precedence %} Similarly, if an organization, repository, and environment all have a secret with the same name, the environment-level secret takes precedence.
Limits for secrets
You can store up to 1,000 organization secrets, 100 repository secrets, and 100 environment secrets.
A workflow created in a repository can access the following number of secrets:
- All 100 repository secrets.
- If the repository is assigned access to more than 100 organization secrets, the workflow can only use the first 100 organization secrets (sorted alphabetically by secret name).
- All 100 environment secrets.
Secrets are limited to 48 KB in size. To store larger secrets, see AUTOTITLE.
When {% data variables.product.prodname_actions %} reads secrets
Organization and repository secrets are read when a workflow run is queued, and environment secrets are read when a job referencing the environment starts.

{% data variables.product.prodname_dotcom %} automatically redacts the following sensitive information from workflow logs.
