Securely Using Online Banking: The Key Rules
Here’s how you protect your account from fraudsters: correct login, secure authorisations, common phone scams, and what to do if something goes wrong.
Updated on 1/11/2026
Straight to the bank
Access your online banking only through the banking app or by typing in the address yourself or using a saved bookmark. Never click on links from emails, texts or search ads – fake bank pages even show up in search results.
Read the details before you confirm
Whether it’s an app approval, a TAN generator or a code: check exactly what you’re approving before you confirm. If a transfer, a new device or a card payment appears that you didn’t initiate yourself, stop immediately. Scammers often disguise transfers as a “security check” or a “refund”.
The most common scams
- Fake bank employee on the phone: the number on your display looks authentic but is spoofed. The caller asks you for approvals to supposedly stop fraud. Real bank staff never ask for codes or approvals.
- “Your account will be locked” message: the link leads to a fake login page.
- “New security procedure”: you’re asked to set up the app again via link or phone call – in reality, the scammers link their own device to your account.
- Remote access: claimed support wants to access your computer while you open banking.
Basic protection in five steps
- Keep your phone, computer and banking app up to date.
- Use a strong, unique password for your banking that you don’t use anywhere else.
- Lock your phone with a PIN or fingerprint.
- Turn on notifications for every transaction so you immediately spot anything unusual.
- Set a daily limit for transfers that fits your everyday habits.
Banking while you’re out
In unfamiliar Wi-Fi networks – at a café, hotel or train – you can’t know who runs the network. A VPN encrypts your connection, ensuring no one can read your data or silently redirect you. Even simpler: use your mobile data instead of an open Wi-Fi network for banking on the go.
If something goes wrong
- Immediately call your bank or have your card and access blocked – in Germany you can do this 24/7 via the emergency lock-in hotline 116 116.
- Change your banking password from a clean, safe device.
- Collect evidence and file a police report.
