The last and most important step of the sign-up user flow is to ask users to confirm their accounts. The most common ways to do so are:

• Via phone: Send a verification code to users' phone numbers and asking them to enter it into the app. Compared to email, phone verification is a more secure way to guard against fake accounts.^[1]
• Via email: Send a link to their email that they need to activate. If users go with social sign-up, the link should be sent to the email they used for registration at the social media app or website.

Most social media apps or websites allow unauthorized users to view content without the possibility of connecting with other users, posting updates, or performing other essential activities.
