To keep your CVV number safe, follow these simple tips:
- Don't write your CVV number down anywhere it could be accessed by someone else.

Protecting your CVV number is crucial to prevent unauthorized charges to your account. Don't share your CVV number with anyone, even if they claim to be from your bank or the credit card company.
Writing your CVV number down anywhere it could be accessed by someone else is a big no-no. I've seen people write their numbers on sticky notes and leave them on their desks, which is just asking for trouble.
Make sure you're signed out of any shopping or banking websites when you're done using them. This is a simple habit to get into, but it can save you a lot of hassle in the long run.
If you're using a public computer, use a virtual keyboard to enter your CVV number. This will help prevent keyloggers from capturing your number.
