## Transcript

### Introduction

**0:00** · \[MUSIC PLAYING\] RODY DAVIS: Hi, I'm Rody, for "The Developer Show."

**0:07** · This is your weekly update on the coolest Developer news from Google.

### MFA, Blocking functions, and more come to Firebase Authentication

**0:11** · First up, we have some exciting new features for Firebase authentication.

**0:14** · You can now provide even better protection for your users with multifactor authentication.

**0:19** · Adding MFA into your existing apps is very straightforward and is coming to Firebase UI and all the platforms very soon.

**0:26** · In addition, there are new blocking functions that let you check if a user can create an account or log in before finishing the auth flow.

**0:33** · With the latest stable releases of Firefox and Safari, there are some new CSS features that just become possible across all the browsers.

### New to the web platform in July

**0:41** · First up is the backdrop filter, which makes it possible to apply effects in the area behind the element, such as a grayscale invert or blurring.

**0:49** · Next, we get the scroll-snap-stop property, which makes it possible to control the snapping behavior of scrolling elements.

### Prepare your app to support predictive back gestures

**0:56** · With the Beta 4 release of Android 13, you can now update your app to support the new predictive back gesture.

**1:02** · This allows you to show a preview of what will happen when you're swiping back, and this feature requires the app to explicitly opt into the feature and the setting to be enabled in Developer Options.

**1:12** · After Android 13, this will be ignored.

### Brushing up on Compose Text coloring

**1:15** · In Jetpack Compose 1.2.0, it is now possible to add gradients and other color options for text rendering using the regular and shader brush.

**1:23** · This approach uses the brush API instead of using Canvas or Modify or Blend modes to make it a lot simpler to use and to build custom textiles.

**1:31** · Quick note that this will not work with emojis, as they're skipped by the shader.

### Profiling XNNPACK with TFLite

**1:36** · And in case you missed it, XNNPACK is now available on 2.9.1 and later and is a highly optimized library for floating point neural networks interference operators on multiple platforms.

**1:46** · This library will help in getting the best performance possible for your models while no longer having the profile accumulate all the delegated operators into a single row.

**1:54** · To learn more about this and all the week's stories, make sure to check out the description box for all the links.

**2:04** · Thanks for watching, and we'll see you next week.

**2:07** · Delegated operators into a single row.

**2:09** · I'm going to do a redo of that section.

**2:11** · There's a lot in there.
