The main authentication applications of multiple factors to protect their accounts
NEWNow you can listen to News articles!
Computer pirates often exploit reused passwords, obtaining access to multiple accounts if only one is compromised. To stay safe, use strong and unique passwords for each account and change them regularly. However, passwords alone are not enough. That’s where multifactor authentication applications enter.

What is multifactor authentication?
Multifactor authentication (MFA) adds an additional layer of protection to your accounts. Instead of trusting only a password, MFA requires that you verify your identity using two or more methods. These may include SMS codes, authenticator applications or physical security keys.
MFA vs. Two factors authentication
The authentication of two factors (2FA) is a type of MFA that uses exactly two verification methods. MFA, on the other hand, can involve two or more factors. For example, log in to your bank may require a password and an application code: this is MFA in action.
What multifactor authentication method is better?
Not all websites and applications admit each type of MFA, so your choice may depend on what is available. This is how the main options are compared:
- Physical security keys: These offer greater security and are resistant to phishing and malware. However, they are less convenient and not universally admitted. If you lose your key, you will need a backup method.
- SMS text messages: SMS is easy to use and widely compatible, but it is the least safe. Computer pirates can intercept or redirect text messages, which makes this method vulnerable.
- Authenticator applications: These applications achieve a balance between security and convenience. They are less likely to be pirate and work on most smartphones. However, not all services admit them, and it is possible that you need an internet or cellular service to use some characteristics.

Why do banks use SMS for MFA?
Many banks use SMS for the authentication of two factors because it is easy to configure and works on any phone. However, SMS is not the safest method. Authenticator applications and physical security keys offer better protection against modern threats.
Is there a unique solution for everyone?
Unfortunately, there is no universal MFA solution for each account. The best focus is to use the most strong MFA method that each service admits. Whenever possible, choose an authenticator application or a physical security key on SMS.

Aegis authenticator

AEGIS AUTHENTICATOR AP. (Aegis)
The AEGIS Authenticator application is a free option for Android users. It is a great application to protect their online accounts from computer pirates and phishing. Add an additional security layer generating unique codes that must be entered only with your password. In this way, even if a hacker steals his password, he will not be able to access his account with his phone. The AEGIS Authenticator application also allows you to customize and organize your accounts, backups and restore your data, and use it offline.
Why you should also use a password administrator
While multifactor authentication adds critical protection, it works best when combined with strong and unique passwords for each account. That’s where a password administrator enters. Instead of trying to memorize dozens of complex passwords, a password administrator stores them safely for you and automatically fills them when necessary. You can generate strong and random passwords, store them in an encrypted and synchronize vault through your devices so that you always have access. The use of NordPass together with the authentication of multiple factors is one of the best strategies to maintain their personal accounts and data safe from computer pirates.
