QR Codes for Public Profiles. Generate a QR code for yourself or any user with a public username – as well as any public group, channel or bot. Tap the QR code icon next to a person’s username or on a chat’s info page, customize its appearance, then print, post or share the code anywhere. You can generate a QR code for your own profile from the Settings page – those you share it with can add you as a contact via your public username or your phone number link. Users who don’t have a username and hide their phone number from everyone generate temporary QR codes that follow their privacy settings. forwarded from Natasha 6883631308
