If you cannot add Teammates, use the Multi-device feature on Authy. To provide secure access to multiple users of your account we recommend adding Teammates and enabling two-factor authentication for each Teammate. When prompted, enter the 7-digit token sent to your device, or generated by the Authy App. Once set up, you will always be required to use Two-Factor Authentication to perform security-restricted actions in your SendGrid account, such as logging in or changing your Two-Factor Authentication settings. If you have selected the Authy App, go to your app, and enter the generated code. If you opt to receive a text message with your authentication token, look for the text message and enter the code that you receive. Enter a code sent to your mobile phone that is generated by SendGrid.Īfter you create a setting for Two-Factor Authentication, log in as you normally would.If you use Authy, enable the Authy backup feature to help prevent getting locked out of your account. ![]() The Authy App allows you to authenticate over WiFi if you do not have cellular service and allows you to send your code as an SMS message. Generate a verification code with the Authy App. ![]() Once you have confirmed access to your account email address, you may choose from 2 different verification methods when using two-factor authentication: If you need to update your email address, click the pencil icon to update to an email address you can access, send a confirmation email, and visit your inbox to confirm your email address by clicking the link in the email address change confirmation email. You can do this by visiting your Account Details and reviewing your email address under Your Account > Personal Info. Setting Up Two-Factor Authenticationīefore setting up two-factor authentication, ensure you have access to your account email address. Enabling 2FA does not require an Authy account, but if you have one, you will be able to use either the Authy App or SMS messages. This is a weaker security model because it makes Authy a point of failure for all of the other sites.Twilio SendGrid’s Two-Factor Authentication can be configured to accept a code sent to your mobile phone either via the Authy App, or an SMS message. Instead, you are proving that you know something (your password), and have authenticated with someone else (Authy's cloud storage). This is intended to be for convenience, so that if you lose or replace your phone, you won't have to reconfigure TOTP on all of your accounts.īut it also means that you are defeating the core purpose of 2FA: You are no longer proving that you both have something and know something. When I last investigated it, it stored the secret from step (1) in the cloud by default. However, a malicious client implementation could hand the secrets over to an attacker, who could then impersonate you for 2FA purposes, so you should only use client apps which you trust.Īll that being said, I have some pretty strong reservations about Authy in particular. This is an open standard, and by design, anyone can implement either half of it (client or server).
