Fomo screen lock and PIN lock: how to lock fomo on your devices

fomo has two device locks. In the mobile app, Screen Lock asks for Face ID, Touch ID or your fingerprint every time you open fomo. On the web, PIN lock asks for a six-digit PIN when you open fomo in a browser. Both are optional, both live under Settings, then Security, and both are separate from multi-factor authentication, which is what actually guards withdrawals, sends and key exports.

What are fomo Screen Lock and PIN lock?

They are the answer to a simple problem: your phone or laptop is unlocked, and someone else picks it up. fomo’s help center describes Screen Lock as protecting “the app itself”, and its new security checklist says the point is that nobody who picks up your phone can open fomo. PIN lock does the same job in a browser, because, as fomo puts it, the web app has no biometric option.

That last row is the one most people get wrong. A lock on the screen stops a casual snoop. It is not the check that stands between someone and your money; that is MFA, covered below.

How do you turn on Screen Lock in the fomo app?

fomo’s security checklist gives the route in the phone app:

1. Open the Portfolio tab.
2. Tap the gear icon to open Settings.
3. Tap Security.
4. Switch on Screen Lock.

From then on, fomo asks for Face ID, Touch ID or your fingerprint each time you open the app or come back to it. fomo’s web article describes Screen Lock as “your device biometric”, so check that Face ID, Touch ID or fingerprint unlock is enrolled on the phone itself first. fomo does not publish a delay before the app relocks, and it does not describe a passcode fallback inside fomo if the biometric fails, so test the lock once right after you turn it on. Our tab-by-tab guide to the app shows where Settings sits among the other screens.

How does PIN lock work on fomo web?

On a desktop, open the account menu at the top of the page, choose Settings, then Security, and turn on PIN lock. fomo’s web help article adds two details that matter in practice:

• It follows your account, not one browser. fomo says the PIN lock “is saved to your account, so once it is on, fomo on the web asks for your PIN in every browser you sign in to.”
• Each browser unlocks separately. Entering the PIN on your laptop does not unlock fomo on another computer.

Because the PIN is the only lock on the web, pick six digits nobody could guess from your birthday or phone number, and do not reuse your phone’s passcode. More on what else differs on desktop is in our fomo web app guide.

How are Screen Lock and PIN lock different from MFA?

fomo’s MFA article says the Security screen holds Screen Lock in the app and PIN lock on the web, and that they lock the app on one device and are separate from MFA. Its security article is blunter: MFA is the protection for withdrawals, sends and private key exports, not Screen Lock. Here is what each layer covers, according to fomo’s help center:

MFA is set on your wallet, so turning it on in the app turns it on for the web too. If you only switch on one thing, make it MFA; our fomo two-factor authentication guide covers setup and the no-recovery-codes catch. Screen Lock and PIN lock are the second layer, and they cost you a glance or six digits.

What if you forget your PIN or lose your phone?

fomo’s help articles do not describe a forgotten-PIN flow or say what happens after several wrong PIN attempts. What is documented:

• Contact support from inside fomo. In the app: Portfolio tab, gear icon, Help and Support, then Contact support. On the web: hover over your profile picture and choose Contact support. Our guide to contacting fomo support lists what to include.
• Your funds are not tied to the device. fomo says reinstalling the app does not affect your account, balances or positions, and the wallet is tied to the login you created it with.
• There is no “sign out everywhere” button. fomo’s sign-out article says logging out only ends the session on that device; to cut off a lost device, change the password on your Apple ID or Google Account.

A lost phone with Screen Lock on is an inconvenience. A lost phone without it, and without MFA, is an open door. If anything has already moved, read what to do after an unauthorized fomo transaction.

How else can you protect fomo on a shared device?

fomo’s security checklist goes further than the two locks. The steps that fit a shared or public screen:

• Hide your balance. In the app, tap the balance at the top of Home to mask it; on the web, choose Blur balances from your profile menu or press Cmd+B on a Mac, Ctrl+B on Windows. fomo says this is a display setting saved on that device only, and it hides your own figures, not other traders’ or your row in a token’s holder list.
• Use a separate browser profile for fomo, with no extensions installed in it, and never run a script or bookmarklet someone else gives you.
• Only use fomo.family, typed yourself rather than reached through a link. Our fomo family official website page lists the real addresses.
• Log out when you are done on a shared or public computer, and keep the phone, browser and fomo app updated.

Which security settings should a new fomo account turn on first?

For someone who has not opened an account yet, the order matters more than the settings themselves:

1. Open a referral link before you sign up. The 10% fee discount from a fomo referral link only attaches at sign-up; the step-by-step sign-up guide walks through it.
2. Secure the Apple ID or Google Account you sign in with. fomo’s checklist asks for a strong, unique password and two-factor protection there, preferring a passkey or hardware key over SMS codes.
3. Turn on MFA and back up the authenticator entry, before any money arrives.
4. Turn on Screen Lock on your phone, and PIN lock if you will use the web.
5. Then fund the account.

None of these settings protect you from a token that loses its value or from a fake site asking you to connect a wallet; our guide to fomo scams covers those, and the fomo safety overview explains how the wallet keys themselves are held.
