A magic link is a simple and secure way to log in to a website or app without using a password. Instead, you enter your email address, and then you receive an email with a unique link. When you click this link, you are automatically logged in. Some benefits: It's user-friendly: You don't have to remember passwords, safe: The link is temporarily valid and can only be used once and less risk of hacks: There are no passwords that can be stolen or leaked.
