AutoFill Codes on iPhone
On iOS 18 and later, the Slashy app can offer emailed one-time codes above the keyboard in matching apps and websites, so you can fill a code without switching to your inbox.1
Turn it on
In the Slashy iOS app, open Settings > Mail > Verification code AutoFill and tap it. You can also tap Enable on the AutoFill card that appears on an email containing a code.
2
Follow the iOS prompt
iOS asks you to confirm Slashy as a source for verification codes.
3
Use it
When a site or app asks for a code, Slashy suggests the code from the matching email above the keyboard. Tap to fill it.
Set Up the Automation
1
Open the agent sidebar
Press
Cmd+/.2
Create the trigger
Type: “Create an email automation: when I receive an email with a verification code, OTP, or two-factor authentication code, send me the code on iMessage immediately.”
3
Confirm
The agent creates a trigger matching common OTP patterns: subject lines with “verification code,” “security code,” “one-time password,” plus body content with 4-8 digit codes.
How It Works
- Verification code email arrives
- Trigger fires within seconds
- Agent extracts the code (not the full email)
- You receive an iMessage: “Your verification code from GitHub: 847291”
What Gets Detected
- Numeric codes (4-8 digits) and alphanumeric codes
- Magic links with embedded tokens
- Codes in subject lines or email body
- Codes from banks, SaaS apps, social platforms, developer tools
Customize the Trigger
- Reduce False Positives
- Catch More Codes
- “Only forward codes with ‘verification’ or ‘security code’ in the subject”
- “Don’t forward marketing emails that contain numbers”
