The first time you ship a product that authenticates through Nafath, the effect on onboarding metrics is immediate and honest — the drop-off you used to see on password creation just disappears. It is the single best identity decision a team can make in the Kingdom right now.

And then the second-order questions arrive

Session lifetime. Nafath gives you a moment of verified identity; how long do you extend that trust in your product? Too short and you re-prompt into oblivion; too long and you break the security expectation the user came in with.

Delegation. A parent authenticating on behalf of a child. A caretaker authenticating on behalf of an elder. Nafath is a per-person identity; your product is not. That gap has to be modelled or you will have a support inbox full of angry families.

Fallback. What happens on Nafath incident days? A product that hard-codes Nafath as the only path to sign-in is an outage away from unreachable — and that is a conversation you want to have before it happens, not after.

The pattern that works

Treat Nafath as the identity source, not the session store. Store your own session with a defensible lifetime and refresh policy. Delegation is a first-class model in your product — one Nafath identity can hold multiple in-product personas. Fallback is a documented policy with a manual path that a service desk can invoke without a code change.

None of this is exotic. All of it is easy to miss during the first sprint, because the happy path is so unusually smooth.
