A very common situation is when you need to enter an access code sent via SMS to your smartphone to confirm your identity in a desktop Internet browser. Often this required taking out the phone and manually copying the code.
Chrome 93 supports the Web One Time Password (WebOTP) interface, so if any website also uses this technology, your browser will automatically detect that your phone has received the code.
This, of course, requires an Android phone. In addition, the phone and desktop browser must be subscribed to the same Google account.
You can try out the feature now in the beta version of Chrome 93 on the demo page here.
Unfortunately, the feature is dependent on the Chromium web engine and is currently not supported on iOS. On the other hand, the owners of Apple technology do not need this, because similar functionality has been introduced in it at the system level for a long time.
