fallbackRefreshTokenHashPeppers property

List<String> fallbackRefreshTokenHashPeppers
final

Optional fallback peppers for validating refresh tokens created with previous peppers.

When rotating peppers, add the old pepper to this list to allow existing refresh tokens to continue working. The system will try refreshTokenHashPepper first, then each fallback pepper in order until a match is found.

This is optional and defaults to an empty list.

Implementation
