Using this information, they will be able to access your email account with your details as you do. The only other way to get into a Yahoo! Mail address is if a virus is planted on the victim’s computer. A trojan or keylogger virus will send any cookies or typed information to a hacker who can then use it to gain entry to your account.
All users of Yahoo! Mail are advised to use strong passwords that cannot be guessed by other individuals. If you have a password that relates to your personal information, such as a pet or date of birth, it can be easier for anyone with this information to hack your account. To prevent hackers getting into your Yahoo! Mail account, there are a number of precautions you can take. Make sure that your password is a combination of numbers and letters, preferably both uppercase and lowercase. Try not to use the same password for several different purposes. If a hacker does manage to get into your email account, they may automatically try the same password with any online banking or social network sites. If possible, change your password regularly using a different combination of words and numerical values.
