Ask HN: Why not to use passwordless login?
Plenty, both in terms of security and UX:<p>1.) It&#x27;s less secure (unless the email is encrypted, which in most cases it is not).<p>2.) If you use GMail with several accounts and POP3 you&#x27;ll have to wait until GMail sees fit to fetch the email.<p>3.) Password managers provide both a superior UX and superior security. So, by all means at least provide a password-based login as an alternative (which admittedly defeats the purpose for the operator to have a less complex authentication system to worry about).
