Every login option you add is something to build, test and support. A visitor who hits a login wall they do not like simply leaves, so the choice is a business decision as much as a technical one.
This guide compares the four common options in plain terms and ends with a prompt you can paste into Uttra to get the one you picked.
Start with one or two login methods, not four. Email plus Google suits most sites; add phone OTP only if your customers expect it and you accept the SMS cost, and add Apple if you ship an iPhone app.
Email and password: familiar, but you carry the weight
Everyone has an email, so this works for every audience. The cost is on your side: passwords must be stored hashed, never as plain text, and you need verification and password-reset emails that actually reach the inbox.
A lighter variant is the magic link: the user types their email and clicks a link you send. No password to forget, but it depends on email arriving quickly.
Phone OTP: how many users in the Gulf expect to sign in
In Saudi Arabia and the wider GCC, people are used to receiving a code by SMS for banking, delivery and government apps, so a phone login feels natural and avoids typed passwords.
Be honest about the cost: sending SMS needs a third-party provider with its own per-message fees, and delivery can be slow or blocked. Keep the provider key as a project secret, limit how often a number can request a code, and never put the key in chat or in code.
- Good for: shops, bookings, delivery, local services.
- Watch out for: SMS costs, delayed codes, people changing numbers.
Google and Apple: one tap, no password
Sign in with Google removes passwords entirely and is trusted by most users with a smartphone. It needs a free developer setup on Google's side, which you do once.
Sign in with Apple matters mainly if you publish an iPhone app that also offers other social logins, where Apple's rules ask you to include it. For a plain website it is optional. Add it when many of your users are on iPhones and care about hiding their email.
National ID login: a different category
Government sign-in such as Nafath is built for services that must verify a real person, such as financial or official services. It has its own approval process and rules, so do not plan it for a normal shop or blog. If you need it, check the provider's requirements first.
This is general information, not legal advice. If you store personal data, read the data protection rules that apply to your customers, such as the PDPL in Saudi Arabia.
A prompt you can paste
Tell Uttra the audience and the methods in one message, and say where secrets go:
"Add customer accounts to my store. Let people sign in with email and Google. Add a forgot-password flow, a profile page and a logout button. Store any keys as project secrets, and show the login in Arabic with RTL layout."
