Beginning in November 2022, if a change set or package includes an authentication provider with a consumer secret defined, the consumer secret is changed to a placeholder value. You must insert the consumer secret manually after deployment. Beginning with the Spring ’23 release, this change applies to all change sets and packages, including those generated before November 2022. When you import an authentication provider, the consumer secret is treated as a plaintext value, even if the value was encrypted when the authentication provider was created.
Where: This change applies to Lightning Experience and Salesforce Classic in all editions.
