Why use passwordless forms with Arengu?

Reduce signup friction by eliminating passwords

Opt for a passwordless flow to avoid friction in your registration forms. Setting passwords is proven to be stressful for users, so why not getting rid of them? 

Increase your conversion rates with single-step, one-click signup forms where users don’t need to set up passwords, remember or type them. Cutting the steps and efforts of your signup forms will pay off, both short and long term.

Reinforce security with a sophisticate authentication method

Passwords can be substituted with other robust authenticating systems, such as magic links or OTPs. Implementing them will help you get rid of authentication vulnerabilities typical from passwords, such as predictability, brute force attacks, or data leaks.

Jump into a more sophisticated authentication method and say goodbye to old-fashioned passwords.

Get qualified, real users

Forget about bots and spam accounts. Magic links and OTPs are superb authentication methods that ensure you get verified users. When sent to the users’ email or phone number, the users’ identity will be implicitly verified. 

Implementing a passwordless auth system that implies identity verification is a way of tackling different issues with just one method.

Powerful alone. Better together.
