Meta has moved Login with Facebook into Open Beta on 27. August 2026 with several new features. The focus is on fewer steps for returning users and less maintenance work for developers: Android and the web get a One-Tap login, while on iOS Meta is improving Limited Login and the switch to the native Facebook app.
One-Tap Login for Android and web
If users are already signed in to Facebook on their device, a One-Tap prompt can now appear. Instead of going through the full login process again, eligible users confirm their sign-in with a single tap.
Meta describes the update as a way to reduce unnecessary friction for returning logins. For operators of apps and websites, this matters most where a drop-off in the login funnel directly costs registrations, returning sessions or the match to an existing user account.
Despite Instagram's stronger growth, Facebook remains a very large part of the Meta ecosystem. According to the latest DSA report, Facebook still reaches a triple-digit million monthly active users in the EU; we placed the latest figures in our article on Instagram and Facebook EU reach.
Limited Login on iOS is meant to cause fewer re-logins
Meta is also updating the Limited Login flow on iOS. The underlying profile data and authentication information can now be refreshed in the background, rather than sending users through a full login again when sessions are outdated.
In addition, the Fast App Switch is being expanded: for suitable iOS logins, the process switches directly into the native Facebook app instead of an in-app browser. Meta expects this to make the flow faster and more familiar.
The features are delivered through the current Facebook SDKs and can be used by developers depending on their integration. Open Beta also means Meta can still adjust the features further.
Why this matters for marketing and first-party data
The update is technical, but it has a clear marketing angle: the fewer users drop off during registration or return, the more sessions can be assigned to a logged-in account. For companies with apps or login areas, this strengthens their own first-party data base and can simplify conversion and retention measurement.
It is not a new advertising targeting feature, however. The changes primarily affect authentication and user guidance. Companies should therefore watch their login funnels and check whether completion rates or drop-off points change after an SDK update.
Meta is working on its platform and safety rules in several areas at once. Another part of this development is covered in our overview of Meta's new teen protection rules and the pressure on TikTok and YouTube.
