The first Android O Developer Preview was released back in March, but now, two months later, people are still finding new features and APIs that will change — albeit not in huge ways — how we use our phones when the new OS launches. One of those new features is an API recently spotted by XDA, which suggests that SMS authentication will be streamlined with Android O.
The current implementation of SMS authentication with apps is definitely imperfect. When an app needs to verify your phone number, it’s basically stuck with one of two options: asking you to manually check your SMS messages to find a code it sent, or asking for total access to your SMS messages to find it itself. This new API will essentially allow access in between those two ends of the spectrum — letting the app find the code without getting access to everything.
