4. Check website carefully when entering password:

Passwords are considered to be the most basic way for us to secure online accounts. Therefore, be careful when sharing passwords through any means such as email, messages, SMS.

If the user is not careful, thoroughly checking that you have entered the password quickly, you will probably lose your account quickly. For example, with phishing SMS like "We detect harmful transactions, enter the password to cancel the transaction".

5. Use different passwords for online accounts:

Typically, users will tend to set a password for all online accounts that are owned. This makes it easier for you to remember your account passwords, not having to worry about losing your account when you accidentally forget your password.

However, it is also because of that convenience that hackers can easily control accounts, as they can detect passwords of other accounts. So how to solve this problem, when you can not set each account a separate password?

6. Be wary of OTP phone numbers:

OTP is the authentication code sent to your phone number and the user is required to enter that code to use the account. However, there will be many cases where you receive a code reset message, in the form of a personal number of 10 to 11 digits, it is definitely a fake form, completely different from the 4 to 6 digital switchboard. Ideally, when you receive a message, you should contact the service company to check all received messages.
