This should reflect the wireframes more:

instead of a yes/no answer it's better to have it has the following:

"Renew Master Secret?"
"Do you want to renew the Master Secret for "<app_name>"?"
[Cancel] [Renew]

"Renew Variant Secret?"
"Do you want to renew the secret for "<app_name>" variant "<variant_name>"?"
[Cancel] [Renew]
