Creating a secure password is the first line of defense in digital life, protecting the use of social networks, emails, financial applications and even your own computer or cell phone. Its importance, then, must be the same given to the services themselves, since no one wants to fall into scams or see personal information leaked.

The basic requirements of how to build a secure password involve the use of uppercase and lowercase letters, special characters like @, # or ! and numbers. The longer the better, with Kaspersky experts recommending using combinations starting at 15 digits — longer combinations are harder to crack.
Passwords must be random. No using dates of birth, document numbers, names of parents, spouses or pets, among other elements that can be guessed by criminals through posts on social networks. Even sequential numbers or complete words, even if “obfuscated” by special characters, are not recommended; prefer letters, numbers and symbols arranged randomly.
It is also important to create a different strong password for each service. If all are the same and credentials are leaked on a platform, criminals may gain access to another account using the same information. Also, nothing to use recycled versions like “password1”, “password2” and so on, even when applied to random combinations, since this facilitates the cracking by software used by bandits.
With so many bills, it can be difficult to remember everything; that’s where password managers come in. Applications function as vaults that store credentials so they can be copied easily; everything is protected by a master key, the only one that needs to be remembered by the user and that must also follow the security requirements mentioned here.
To facilitate the process, solutions of this type also offer a random password generator, with size and parameters defined by the user. On the internet, there are also sites like LastPass, which offer this possibility even for those who are not users of the application.
