Control security within your whole team in your Account Security tab by enabling Single-sign on for your Account.
Single-sign on (SSO) is the ability to have a third party service validate your identity, like Google and Github. Bonsai currently support Google SSO. You can enable Google SSO which offers additional security like multi-factor authentication (MFA).
Individual team members can finalize this setup in their Profile Setting's Security tab.
Once Google SSO is enabled on your account, you will be able to require your team members to log in with Google.
