fomo runs in the browser at https://fomo.family as well as in the iOS and Android apps. You sign in with the same Apple ID or Google account you use on mobile and land in the same account, with the same wallets, cash balance and positions.
Signing in with a different Apple ID or Google account does not open your account. It creates a new, separate fomo account with its own wallets, so always choose the account you signed up with.
If you sign in with the account you signed up with and the web still shows a sign up or create account prompt, tap through it. It loads your existing account and does not create a second one.
What you can do on the web
You can trade tokens and trade perps on the web, with the same perps features as the app, give or take a small difference in presentation.
Your settings, including Language and Security, are under Settings in the account menu at the top of the page (hover your profile picture). Your wallet addresses are under Manage account in that same menu, or under Settings, then Account and addresses.
The web also has a Discover page at https://fomo.family/discover, a trading screen with a live token table, Quick buy, your watchlist and side panels: Discover on the fomo web app.
You can also export your private keys on the web at https://fomo.family/export-key. Never share a private key with anyone, never enter it on any website, and never send it to anyone, including support.
What is different from the app
Card deposits, bank deposits and bank withdrawals are currently available in the mobile app only. On the web you deposit by sending USDC and withdraw to a crypto wallet.
Quick Trades is in the mobile app. On the web you trade from the buy and sell panel on the token page, and the slippage setting is the Swap settings gear on that panel. One-click trading on the web is the lightning button that appears on any row of your open positions list, with buy presets in dollars and sell presets in percent, and Quick buy on the Discover page.
The price impact warning shows every time on the web. The "Don't show again for this token" option is in the app only.
The web app has an optional PIN lock under Settings, then Security. It 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, and each browser unlocks on its own. The app uses Screen Lock, your device biometric, instead.
Multi-factor authentication is shared. Turning it on in either place turns it on for both.
