Is there any way to access data from iPhone inbox(SMS) to ios application to do automatic OTP verification like the one in Android? I shall be grateful for your help.
It is also important that the text message you receive contains something with "code" like
"your passcode is:123456"
or
"12345 is your code to log in"
something along that line.
NOT!
Your App: 12345
you can verify if the code in your text message will work with the .oneTimeCode type by tapping the underlined code in your message. If a dialog pops up that says "copy code", you are good to go. Otherwise you might need to change the text of your message.
