Can I use passwordless authentication with existing users?

Can I switch my existing users to passwordless authentication?

Yes, you can implement passwordless authentication for existing users. It typically involves sending a magic link or a one-time code to their registered email or phone number.

What steps do I need to take to enable this feature?

First, ensure your authentication system supports passwordless methods. Then, update your user interface to allow users to request a magic link or code.

Will my users need to do anything special to set this up?

Existing users may need to verify their email or phone number if they haven't done so already. After that, they can log in without a password.

Are there any security concerns I should be aware of?

Yes, while passwordless authentication can enhance security, ensure that the communication channels (like email or SMS) are secure to prevent interception.
