MFA through an authenticator app, for example, Google Authenticator, Twilio Authy, or Microsoft Authenticator Authy, is the preferred method. You can download one of these apps for free from the Apple App Store or Google Play.

SMS (text message) is a secondary method supported by Coupa. However, this method is available for most countries. If it is not available for your country, select a different authentication method or contact your customer for more options.
