Ask users to confirm destructive actions

Passwords, email addresses, and payment methods fall into the category of sensitive information and an app shouldn't change such data without notifying users and getting their permission. Ask for users' confirmation to update this data via an in-app message, clearly explaining the issue and asking them to confirm this action.

Furthermore, destructive actions like deleting or deactivating an account also require users' consent via in-app messages and/or email. It allows users who might have accidentally selected an action to undo it and prevent serious issues like data loss. Confirmations may appear annoying to some users but they inform them about what's happening in the app and take care of their data safety.

Keep in mind that users don't read instructions and alerts word by word, so make sure confirmation dialogs are concise, direct, and informative. Ideally, users should be able to understand the issue by taking one glance at the heading. Try to sound friendly but avoid inappropriate jokes and goofy or ambiguous headings like "Oops" or "Are you sure?"
