Protect your online accounts with secure passwords . Do not use common terms or simple words as a password, try to create long, at least 12 or 14 characters, and complex credentials, combining uppercase, lowercase, symbols and numbers . Also, a password is more secure if it is changed often. Worried about not being able to remember hundreds of different and overly complicated passwords? Try a password manager like Dashlane, which can securely generate, store, and autofill all of your credentials.
