A: There are a number of standard steps to take regardless of your email provider:
- Use a strong password. The current recommendation is a minimum of 15 characters, in a password that is unique and not used with any other of your websites or services.
- Add 2-Factor Authentication. This significantly adds to the difficulty of accessing your account even if your password is compromised.
- Never allow anyone else to use your computer without first creating a user account for them.
- Install and use a quality antivirus software.
Lastly, as you asked specifically about Yahoo, give some consideration as to why one would continue to do business with a company that was directly responsible for not one, but TWO of the worst cybersecurity breaches in history.
