What is SMS to Slack Forwarding?
SMS to Slack forwarding automatically sends your text messages to a Slack channel or direct message. Teams use this to share OTP codes for shared accounts, receive delivery notifications, or route customer SMS to support channels. Forward SMS connects your iPhone directly to Slack using webhooks, so messages never pass through external servers.
Slack is a widely-used tool for team collaboration, offering flexibility and seamless integrations. With the Forward SMS app for iPhone, you can easily set up SMS forwarding to Slack. This ensures that important messages, like One-Time Passwords (OTPs) or 2-factor authentication (2FA) codes, are sent directly to your Slack workspace for quick access.
