Give every user a secure and simple way in with multi-factor authentication, single sign-on, SCIM provisioning, email sign-in codes and passkeys.
Let your team sign in with the accounts they already use, including Microsoft, Google and Okta. SCIM provisioning adds and removes users automatically as your directory changes, so access stays accurate when people join or leave. Add an extra verification step with multi-factor authentication, or go passwordless with passkeys using face, fingerprint or PIN.
