As much as we would like to get rid of passwords, we must admit that this form of authentication will be around for the foreseeable future. Because passwords are still a primary way to authenticate to computers and websites, it is important to educate people about the dangers of reusing passwords across multiple accounts, and to provide them a way to easily manage the multiple passwords that the typical person has.
Cybercriminals know that it is human nature to come up with a single strong password, then reuse it across multiple platforms. Without tools to help manage multiple passwords, there is simply no way for a person to memorize them, which leads to this reuse. Bad actors know that if they can extract the username and password from a breach, that the odds are good that many of them will also be used in other places, so they try them at major banks, email providers, social media platforms and even large retailers.
