Secret redaction
Storing credentials as Azure Databricks secrets makes it easy to protect your credentials when you run notebooks and jobs. However, it is easy to accidentally print a secret to standard output buffers or display the value during variable assignment.
To prevent this, Azure Databricks redacts all secret values that are read using dbutils.secrets.get(). When displayed in notebook cell output, the secret values are replaced with [REDACTED].
For example, if you set a variable to a secret value using dbutils.secrets.get() and then print that variable, that variable is replaced with [REDACTED].
Warning
Secret redaction for notebook cell output applies only to literals. The secret redaction functionality does not prevent deliberate and arbitrary transformations of a secret literal. To ensure the proper control of secrets, you should use Access control lists (limiting permission to run commands) to prevent unauthorized access to shared notebook contexts.
