Q: Do you support SMS or phone-based sign-in?

Atlas supports SMS one-time codes for sign-in and verification. Because SMS requires a delivery gateway, you configure an SMS provider in the dashboard's messaging settings; once connected, SMS codes are available in your sign-in flows and can serve as a delivery channel for verification. If you'd rather avoid SMS (cost, deliverability, SIM-swap risk), Atlas's email one-time codes, magic links and passkeys give you passwordless options with no external provider to configure. See the messaging and SMS guide.

Yes — Atlas supports one-time codes over SMS as a sign-in and verification method when you configure an SMS provider. Email one-time codes and magic links work out of the box with no provider setup.
