SMS Relay

SMS Relay

Your main iPhone's 2FA codes, on this one.

1. Set up the Shortcuts automation on your main iPhone (Main iPhone setup, below).
2. Codes then arrive on this iPhone as notifications from the real sender, with the code on the clipboard.
3. Settings › SMS Relay turns copying or duplicate hiding off.

Login and 2FA codes texted to your main iPhone's number show up on this iPhone, as a notification from the real sender.

• A Shortcuts automation on your main iPhone forwards only code texts, over iMessage, to your own number.
• SMS Relay rewrites that notification to show the real sender and the text.
• The code goes straight to the clipboard.
• If the same code also arrives as an iMessage, the second copy is hidden.

1. On your main iPhone: Shortcuts › Automation › New › Message. Message Contains: a single space. Run Immediately, Notify off.
2. Add Match Text on the message's Content, with the pattern below.
3. Add If (Matches has any value) › Send Message to your own number: “[SMS] ”, the Sender, a line break, then the Content.
4. Mute your own-number chat on the main iPhone.
