Databricks redacts secret values that are read using 

dbutils.secrets.get(). When displayed in notebook cell output, the secret values are replaced with 

[REDACTED]

Although it is not recommended, there is a workaround to see actual value with a simple 

for loop trick. So, you will get the value separated by spaces.

value = dbutils.secrets.get(scope="myScope", key="myKey")
 
for char in value:
    print(char, end=" ")
 
Out:
