Hi @teaxyz 

Hope you're doing well

Over here you can find a detailed explanation of user sign in options already built in Lucid.

Maybe, depending on your needs and plan, you can choose the best sign in option that fits your needs (e.g. e-mail confirmation, SAML, specific SSO ...)

To elaborate further, the document mentions the following:

Note: Lucid users can set up multi-factor authentication (MFA) via SSO login with Google or Microsoft. Enterprise accounts can set up multi-factor authentication via an Identity Management Provider (IDP).

And even, in case you need a more how to approach, Lucid's Support Team already addressed similar issues on this, here. 

Cheers
