Why you are seeing this page
fomo shows the Security warning page when you arrive at fomo on the web from a website or URL we treat as suspicious. Seeing it does not mean something has happened to your account. It means the page that sent you here is not one we trust, and anything you did on it, especially saving a bookmark it offered or entering your details, may have put your browser at risk.
Before you log back in, work through the three steps below. They take a few minutes and they close the most common ways a bad site keeps a hold on your browser.
Step 1: Clear your cookies
A suspicious site can leave data behind in your browser. Clearing your cookies removes it. This signs you out of most websites, including fomo, and that is expected.

Step 2: Remove any bookmarks you added recently
Open your bookmarks and delete anything you added recently, anything you do not remember adding, and anything a website asked you to drag to your bookmarks bar. A bookmark can hold code instead of a web address, and the section on bookmarklets below explains why that matters.

If you want to see which site sent you to fomo, your browsing history shows it:
Step 3: Open a new browser session
The clean way to do this is a new browser profile that you use only for trading. A profile is a separate copy of your browser with its own cookies, bookmarks, extensions and history, so nothing from the browser you were using carries over into it.
Create the new profile, and keep it empty: no extensions, no bookmarklets, and no other sites signed in. Use it for fomo and nothing else.

Safari on Mac:
Microsoft Edge:
On iPhone or Android, the fomo app is the equivalent of a clean profile.
In the new profile, type fomo.family into the address bar yourself. Do not go back through the link that sent you here. Log in with the same Apple ID or Google account you signed up with.
Once you are in, look through your recent activity. If you see a trade, a transfer or a withdrawal you did not make, contact support right away and do not add funds to that wallet until we have looked at it with you.
Bookmarklets: what they are and why they are risky
A bookmarklet is a bookmark that holds a piece of code instead of a web address. When you click it, that code runs on whatever page you have open, inside your browser, with the same access that page has.
That is what makes them dangerous. If you click a bookmarklet while you are signed in to fomo, the code runs inside your signed-in session. It can read what is on the page and take actions as you, without ever needing your login. Many bookmarklets also load their code from a website every time you click them, so whoever controls that website can change what the bookmarklet does at any time, including long after you saved it. A bookmarklet that was harmless when you added it can be turned into one that steals your data or moves your funds.
Sites built to steal from traders often rely on exactly this. They offer a "tracker", "sniper", "claim" or "verify" button and ask you to drag it to your bookmarks bar. That button is a bookmarklet.
To stay safe:
Never click a bookmarklet in a browser profile that is signed in to fomo, or to anything else that holds money or personal information.
Only save a bookmarklet from a source you trust, and only if you understand what it does.
If you use one, do it in a different browser profile with nothing signed in, never in your trading profile.
Do not enter account logins, card details or personal information on a page you reached through a bookmarklet.
Treat any site that asks you to drag a button to your bookmarks bar as a warning sign.
If you have already clicked a bookmarklet while signed in to fomo, work through the three steps above, then check your recent activity and contact support if anything looks wrong.
Your private key
No one at fomo will ever ask for your private key, and no website, bookmarklet, form or support chat ever needs it. If you typed your key anywhere outside the fomo app, treat that wallet as exposed and contact support straight away.
