Different actions need different assurance. Step-up rechecks identity or approval for higher-risk operations.
Evaluation approach
Classify new recipients, recovery, privilege changes and exports. Bind required verification to operation content.
Application example
Approval for an address change must not also authorize an unrelated payment. Users should see what they approve.
Limits and considerations
Without server enforcement, another verification screen remains an interface control.
Can approval move to another operation?
Associate approval with the actual amount, destination or privilege change. Changed fields require renewed verification; a generic success flag is not transaction authority.
Checks and decisions
- Identify high-risk actions
- Bind approval to content
- Enforce server-side
