Email verification

These are all methods on the SignUp class that allow you to verify a user's sign-up request via email.

`prepareEmailAddressVerification()`


function prepareEmailAddressVerification(params?: PrepareEmailAddressVerificationParams): Promise<SignUp>;

Helper method that allows you to initiate a verification process for an email address. It basically sends a one-time code to the email address already supplied to the current sign-up.

The defaults of this method are equivalent to calling SignUp.prepareVerification('email_code').

`PrepareEmailAddressVerificationParams`

Name	Type	Description
`strategy`	`'email_code' \| 'email_link'`	The verification strategy to validate the user's sign-up request. The following strategies are supported: `email_code`: Send an email with a unique token to input. `email_link`: Send an email with a link which validates sign-up
`redirectUrl`	`string`	The URL to redirect the user to after the verification process is complete. Only supported on `email_link`, `oauth_<provider>`, and `saml` strategies.

`attemptEmailAddressVerification()`


function attemptEmailAddressVerification(params: AttemptEmailAddressVerificationParams): Promise<SignUp>;

Helper method that attempts to complete the verification process for an email address. It basically verifies that the supplied code is the same as the one-time code that was sent to the email address during the prepare verification phase.

This is equivalent to calling SignUp.attemptVerification({strategy: 'email_code', ...params}).

`AttemptEmailAddressVerificationParams`

Name	Type	Description
`code`	`string`	The code that was sent to the user via email.
