password. For example, if we are traveling with luggage in a public transport like a bus, train or
aeroplane, we can ensure that our luggage is not opened by any other person by securing the luggage

with the lock that can open only with a secret code or password.
We keep our important documents in a safe cupboard and lock it up with a key so that they do not get
accessed by people whom we do not trust. Similarly, in a computer we set a password as key so that
our documents or files that are stored remain safe or secret.

Passwords authenticate or enable a person to access or operate a computer, network resource,
Internet, e-mail, bank account, etc. Whether it is banking, online shopping, checking of e-mails or use
of social media, people have to make use of passwords.

guessable by others.

symbols.
· Avoid keeping passwords based on repetition, letters or number sequences.

· Use a combination of uppercase and lowercase.
