Invalid credentials
Check caps lock and keyboard language. Use your username, not your email address.
Signing in to a brokerage is more than typing a password. Here is the order of events, the doors available and what to do when one jams.
Pick browser portal, terminal or phone app. The credentials stay the same, only the screens differ.
Use a password manager, and glance at the address bar before typing.
Usually a prompt on your phone. Match it to your own action and decline anything you did not start.
Check the last-login time shown inside the account. If it looks wrong, change your password and call support.
Check caps lock and keyboard language. Use your username, not your email address.
Open the app by hand, allow notifications and confirm the phone is online.
Repeated failures can lock access. Use the official recovery path, not more attempts.
Try a private window without extensions, then a different network.
Paper and live accounts use separate sign-ins. Make sure you have the right pair.
Move authentication to the new device before wiping the old one.
No. This site has no login form. Use the official address or the official app.
Accounts that hold money use a second factor, commonly approved on a phone, to block stolen-password access.
Use the broker's official recovery process and never share codes with anyone who contacts you first.
