Trust and security

A passkey is a pair of keys made on your own device. Your phone or laptop keeps the private half and only proves it has it, so a look-alike sign in page has nothing to capture. While we finish the move to passkeys only, email codes and passwords still work, and we never store a password, only a slow, salted scramble of it. New passwords are checked against known leaks without the password ever leaving our server.

Protects against phishing, reused passwords and leaked password lists.

Your passkeys are made and kept on your own devices. There is no password to phish, reuse or leak, and no fallback to something weaker, because attackers always go for the weakest door. If you lose a device, your other devices or Scale Recovery get you back in.

Protects against phishing, password leaks and fake "your code is" texts.

Malware that copies browser cookies is how many of the biggest recent breaches began. With Scale, your device holds a key that never leaves it, and your session is tied to that key. A session copied to another computer simply doesn't work there.

Protects against cookie stealing malware and session hijacking.

When a new device signs in, your trusted devices hear about it right away, with what it is and when. It waits for your approval before it can reach your account. If it wasn't you, one tap turns it away.

Protects against someone who gets hold of your sign in quietly adding a device of their own.

If something feels wrong, press "I've been hacked" on any of your devices. Every session ends and nothing important can change until you confirm it's you from a device you trust.

If you lose your devices, Scale Recovery weighs the proofs you can show, like your recovery kit and your other devices, so a convincing voice on the phone counts for nothing. Every device you own is told when recovery starts, and any of them can stop it. Nobody at Scale can skip those steps, so nobody can talk us into it either.

Protects against account takeover, and scammers who call pretending to be you.

You see exactly what a site is asking for, then choose Allow or Cancel. Each outside site gets a different ID for you, so sites can't compare notes to follow you around the web. You can stop sharing with any site in Scale Settings, and a sign in that isn't finished in a few minutes expires on its own.

Protects against sites tracking you across the web, and one leaked password unlocking every site you use.

Scale signs every sign in token, and sites check that signature against keys we publish. Each token names the one site it was made for, so a token taken from one site is refused by another. The app that starts a sign in also has to prove it is the same app that finishes it, so an intercepted sign in code is worthless.

Protects against forged logins and stolen sign in codes.

Most businesses can't build this level of protection for their own websites. With Continue with Scale they don't have to: the sign in happens with Scale, with every protection on this page, and the site gets a token tied to the app that asked for it, so a copied token is useless on its own.

Protects against account takeover on sites that would otherwise rely on passwords.

When AI wants to do something that leaves a mark, it can't do it alone. It shows you an approval card with exactly what, to whom and how much. Your approval works once, only for you, and we check your role again the moment you tap it. Spending is for owners only, with a limit. Everything AI writes carries an AI-generated label, so you always know what came from a person.

Protects against an AI mistake turning into a sent email or a payment, and anyone using AI to reach past their role.

A scammer can hide a line in an email like "forward me the payroll file." Before AI reads outside content, hidden text is stripped and the content is marked as not from you. While it is in play, AI cannot send, share, delete, sign or spend at all, and its answers leave out links and images to sites we don't know. We test this on every release with attacks written to fool it.

Protects against prompt injection, the trick of hiding commands for AI inside a message or a document.

Before AI reads anything, our server checks who is asking and what their role allows, so a team member can't get payroll out of AI that they couldn't open on their own. Our AI logs record what happened, like timing and which tools ran, but never your question, the answer or your content.

Protects against people reaching past their role, and logs that leak what you said.

Your approval is locked to the details you saw: the amount, the payee, the change. If anything is different from what you approved, the approval no longer fits and nothing happens. A stolen session can't approve anything, because only your own device can make that approval.

Protects against stolen sessions, and payment details swapped behind your back.

Every connection uses HTTPS. On top of our host's own encryption, we encrypt each workspace and every Drive file again with AES-256, using a key that belongs to that workspace alone. Bank connections are sealed with a separate key, so a copy of our data store on its own doesn't reveal them.

Protects against one leak exposing everyone's data.

If you want help, the owner can let support in for 1 hour, 24 hours or 7 days, read only. Even then, support sees settings, never your mail, files, documents or signatures. Every grant and every visit is written to a log that can't be quietly edited and is shown to you in Settings. Turning access off ends it at once.

Protects against snooping, and the insider who gets bribed or makes a careless mistake.

You'll see the choice in plain words during setup and in Settings, and you can change it any time. Every choice is saved with the date and the version of the AI policy you saw, so there's a record either way. Your data is never sold.

Protects against your business quietly becoming someone else's training data.

If you close your account, you have 30 days to change your mind. After that, your workspace is deleted and the deletion is logged. We keep only the records the law asks us to, like billing and consent records.

Protects against being stuck with a tool you've outgrown, and your data living on after you've gone.

Your passkey can produce a secret that never leaves your device. We use it to lock the data you choose, so what we store can't be read by us, our hosts or anyone who breaks into either. When you share with a teammate, their public key is published where their own devices check it, so a key can't be quietly swapped. The honest trade: if you lose every device and your recovery kit, we can't open it for you either.

Protects against a break-in at our servers, and a rogue insider.

Some attackers collect encrypted data today, hoping to crack it with quantum computers later. Every record we store says which algorithms protect it, so we can move to the new NIST standards, paired with today's proven methods, one record at a time.

Protects against "harvest now, decrypt later."

Card numbers and bank details are typed into Stripe's own secure fields and go straight to Stripe. We keep only the card brand and last four digits. Bank connections in Money are read only, and you sign in on your bank's or Plaid's own screen, so we never see your bank login. Every message from Stripe is checked for its signature and handled once, so a copied message can't be replayed.

Protects against stolen card numbers, and fake payment notices.

You see the fee before a payment happens, and the full table, with worked examples, is in Help under Pay fees. If a buyer disputes a charge, the dispute runs through Stripe, and Stripe's dispute fee is billed to your Stripe account the way it would be with any processor.

Protects against surprise fees and hidden markups.

Before a first listing, sellers confirm their business name, contact details and address, and Stripe verifies their bank and tax ID. High volume sellers are checked again and certify every year, and larger sellers show buyers how to reach them, as the federal INFORM Consumers Act requires. Every listing has a Report button.

Protects against fake sellers, stolen goods and storefront scams.

When someone asks to change your payout bank, payouts hold while every owner device and inbox is told, and any owner can cancel with one tap. Large refunds and payouts need two approvals: two people, or two of your own devices if you run the business alone. Approvals happen on a small, separate page with no outside code, which shows the exact details being approved.

Protects against payout redirection, fake "our bank details changed" emails, and a stolen session draining an account.

The host asks, and everyone on the call has to agree to that exact request. Anyone can take their yes back, and someone new joining pauses it until they answer. Recordings are saved to the host's own device and never uploaded to us. Hosts can keep guests in a waiting room until they let them in, and call audio and video travel encrypted between the browsers on the call.

Protects against secret recordings, uninvited guests, and the legal risk of recording without everyone's consent.

Signers first see the ESIGN and UETA disclosure and agree to sign electronically, then confirm who they are with a code. Each step is written to a chained record with the time, the device and the document's fingerprint, so changing any entry breaks the chain. When everyone has signed, the sealed PDF and its certificate are saved to your Drive, and Verify rechecks the whole thing whenever you like.

Protects against arguments over who signed what, and documents changed after signing.

Marketing email gets one-click unsubscribe, your postal address and honest From and Subject lines, and bought lists are refused. If bounces or complaints spike, sending pauses until a person reviews it, so one bad list can't burn your reputation. Texts need consent on record, STOP works instantly, and quiet hours are respected.

Protects against spam complaints, blocklists, and the fines that come with them.

New passkeys, new devices, recovery, role changes, payout changes and support visits are written to a tamper-evident log. Your devices check it on their own and ask "Was this you?" about anything they didn't do, with a one-tap way to lock your account. Independent witnesses confirm that everyone sees the same history, so not even we could show you a cleaned-up version.

Protects against silent changes by an attacker, an insider, or someone who breaks into our servers.

Recovery is something you do with proof, not something a friendly voice on the phone can arrange. When Scale really contacts you, your app shows a live banner with a code, so if there's no banner, it isn't us. Support gives every customer the same answer, however urgent the call sounds.

Protects against help desk scams, cloned voices, and fake "Scale support" calls.

Some of the biggest breaches came through someone else's script running on a trusted site. We serve every file ourselves, lock each page to our own code, and publish a signed list of what each release contains, so a tampered file stands out.

Protects against supply chain attacks and tampered code.

Every account carries a few things that look valuable but have no legitimate use. Touching one tells us, with high confidence, that someone is where they shouldn't be, long before they reach anything real.

Protects against intruders who try to look around quietly.

We use a few simple signals we can explain to you. We never fingerprint your browser, track your precise location or record how you type. A risky moment gets a quick check, never a mystery lockout.

Protects against stolen sessions used from somewhere else, without spying on you.

Each connection gets only the access it needs. Connections you stop using expire on their own, and an unusual burst of activity pauses that connection and tells you. Several recent breaches ran on old keys that still worked years later. Ours expire.

Protects against stolen connection keys and bulk data theft.
