Choose how to sign in

Sign in to your Sigma account. Identity and account access are managed by Vesta Access. Every method reaches the same account.

Use your card where you have a reader; carry a phrase where you do not.

Have a phrase?

An administrator-issued recovery phrase uses this same form and opens only that identity's Account page.

A six-word access phrase works on any device — no reader, no passkey. Type each word; suggestions appear as you go.

Have a registration invitation?

An administrator may give you a one-time six-word invitation to request a new account. It is not an access phrase and does not sign you into an existing identity.

On a shared computer, close the browser to fully sign out — removing your card does not end a certificate session that the browser has already cached.
