Choose your passwords carefully and keep them safe

About Passwords

In today’s life, we are using passwords every day for accessing our e-mail or social media accounts or logging in at our workplace.

Password: "IwG'sA@22.15"

Sentence 2: “Brrr, it’s really cold this morning, - 9 degrees:-(”
Password: “B,irctm,-9d:-(”
