SignRequest recommends you to enable two-factor login as an extra security measure.
Please visit your account page to set this up.
Note: It is not (yet) possible to use two-factor authentication in combination with Zapier. Enabling this setting will disable any Zapier integration you've made, and a (403) Forbidden error will occur in Zapier. The Two Factor Authentication will need to be disabled from the account page to enable the Zapier integration.
For a detailed step by step process on how to enable 'two factor authentication', have a look below.
1. Click 'Enable Two-Factor Authentication' on your account page.
2. Select the authentication method
SignRequest advises you to use the Google Authenticator app (Android, iOS) which you can use to log in with many other services as well.
3. Enter the token
Open your Google Authenticator App on your phone, click '+' to add an additional login and scan the QR code. You can now enter the token.
You should now see the next screen.
4. Create back-up tokens (Optional)
It is also possible to enable 2FA for your signers in the form of a text message verification, or a user password--> Additional 2FA methods
