Unfamiliar domains trigger phishing instincts. Your domain keeps users confident.
Higher conversion
Branded login flows reduce drop-off during sign-up and password reset.
Enterprise ready
Security teams require domain control. Check the box before procurement asks.
Four steps to branded auth
Provision domain
Register your auth subdomain and verify DNS ownership via CNAME.
await authaz.domains.create({
tenantId: "org_123",
domain: "login.acme.com",
});TLS certificate
Authaz automatically provisions and renews TLS for your custom domain.
// Automatic — certificate issued
// within seconds of DNS verification.Apply theme
Push brand colors, logo, and typography to every auth screen.
await authaz.branding.update({
tenantId: "org_123",
theme: {
primary: "#0EA5A4",
logo: "https://cdn.acme.com/logo.svg",
},
});Roll out
Enable per-tenant with automatic fallback host protection.
await authaz.domains.activate({
tenantId: "org_123",
fallbackHost: "auth.authaz.com",
});
