Authentication: design beyond login
Device changes and recovery also establish trust.

Reading context
A short architecture article. The technical reference supports the topic; hypothetical scenarios and assessment proposals are editorial analysis, not accounts of personal implementations.
Original source ↗The architecture decision
A login screen is only one account entry point. Registration, recovery and contact changes also affect who controls an identity. Reviewing them separately can create inconsistent rules.
Practical application
Consider a hypothetical journey with strong login but an email change relying on an old session. Editorial proposal: map every identity change to its trigger, required evidence and account-holder notification.
How to verify
Before release, simulate device loss and a legitimate phone change. Record both barriers and support shortcuts. Assess security and usability together, especially when recovery becomes the easiest route to account takeover.
