Users would benefit from seeing the partial address (similar to what is shown if they decide to change their Recovery Email Address after it has been set) when they are presented with the screen for entering their one-time passcode.
Often users have multiple personal email accounts and they may not immediately remember which they used for their recovery email address. Showing it partially would assist the user with this.
This is in our new authentication release which is pending release any day now!
Thank you for the suggestion!
This is now available!
