One account, and you're in everywhere: no "not another login" sigh required. Sign up with your email or one tap through a social provider, and the same account follows you from the web app to the iOS and Android apps. Behind the curtain, we take the trust part seriously: social sign-ins are brokered through Firebase, and Memr.is checks every token's signature, issuer, audience, and expiry, accepting only providers on the platform's enabled-provider allowlist. But here's the part that matters most: your account is created and owned by the Memr.is identity service, not the provider. Providers are a door, never a cage: link several to one account, see each one's last-login time, and unlink any you've stopped using.
When you're ready to lock things down, the locks are already there. Add a passkey for passwordless sign-in, complete a quick challenge when something needs extra proof, and tuck away recovery codes for the day your phone takes a swim. Your account page lists every active session (device label, client kind, and last-seen time, with the one you're on clearly marked), and any session you don't recognize can be signed out with one click.
And because everyone should really mean everyone: a keyboard-reachable accessibility drawer sits on every signed-in screen with nine controls: light, dark, or system theme, a text-size slider from 80% to 200%, reduced motion, high contrast, a dyslexia-friendly font, underlined links, enhanced focus outlines, increased text spacing, and larger tap targets. The core settings sync to your account, so the setup you dialed in on the couch is already waiting on the church iPad.
