In the digital age, our lives are a mosaic of applications and online services, each protected by a password. This seemingly simple key is the first and most important barrier defending our personal data. However, not all applications offer the same security standards. Some, especially older ones, do not support two-factor authentication (2FA), a level of protection that is now fundamental. A crucial question therefore arises: how can we protect our main accounts when we need to link them to these less secure apps? The solution lies in app-specific passwords, a powerful yet often underestimated tool.
This article explores in detail what app passwords are, why they are essential for digital security, and how to generate them for major services like Google, Microsoft, and Apple. In a European context, and specifically in Italy, where digital culture mixes tradition and innovation, awareness regarding data protection is growing, driven also by regulations like the GDPR. Understanding and correctly using app-specific passwords is not just a best practice, but a necessary step to navigate safely in an interconnected world, protecting our digital identity from increasingly sophisticated threats.
Why a Single Password Is No Longer Enough
The habit of reusing the same password for multiple services is one of the most widespread and dangerous vulnerabilities. An IBM report highlighted how Europe has become the region most targeted by cyberattacks, with a surge in breaches caused by the use of stolen valid credentials. In Italy, as in the rest of the continent, the “human factor” is often the weak link in the chain: weak or reused passwords open the doors to data theft with serious consequences. Using a unique password for every account is the first fundamental step for security. If a malicious actor discovers the password of a less secure service, they won’t be able to use it to access our main email account or online banking, greatly limiting the damage.
Complexity is equally crucial. A robust password should contain at least 15-16 characters, combining uppercase and lowercase letters, numbers, and symbols. However, remembering dozens of complex and unique passwords is an almost impossible task. This is where password managers come into play—tools that securely create and store complex credentials—and app-specific passwords, which offer a targeted solution for a specific problem.
What Are App Passwords and Why Are They Fundamental
An app password is a one-time credential, a long and randomly generated code (usually 16 characters), that authorizes a less secure application or device to access your main account. This type of password should be used instead of your main password only for that specific application. The advantage is enormous: even if the third-party app suffers a breach and the specific password is stolen, your main account remains safe. Malicious actors would hold a key that opens only one small door, not the master key to your entire digital life. Furthermore, you can revoke access to that single app at any time without having to change your main password.
This functionality becomes indispensable when using applications that do not support modern authentication methods, such as “Sign in with Google” or two-factor authentication (2FA). Many desktop email clients (like older versions of Outlook or Thunderbird), calendar apps, or other services that need to sync with your Google, Microsoft, or Apple account fall into this category. Without a dedicated password, you would be forced to enter your main password, exposing it to unnecessary risks, or to disable important security measures. The security of your account should never be a compromise.
Practical Guide: Generating App Passwords
Creating a specific password is a simple process and very similar across major service providers. The fundamental requirement is to have two-factor authentication (2FA) active on your account. This is a non-negotiable security prerequisite that adds an essential layer of protection.
App Passwords with a Google Account
To generate an app password with your Google account, the first step is to access your account management. Navigate to the Security section and, if you have already activated 2-Step Verification, you will find the App passwords option. Clicking on it will ask you to enter your account password again for confirmation. At this point, you can select the type of app (e.g., Mail, Calendar) and the device on which you will use it. It is also possible to enter a custom name to recognize it easily. Once you click “Generate”, Google will show you a 16-character password. Copy this password and paste it into the password field of the application you are configuring. Remember: this password is shown only once, so make sure to enter it into the app immediately.
App Passwords with a Microsoft Account
Microsoft also offers a similar feature to protect access via apps that do not support 2FA, such as older versions of Office. To create an app password, sign in to your Microsoft account and go to the security dashboard. Look for advanced security options and scroll down until you find the App passwords section. By clicking on “Create a new app password”, the system will generate one to use in the desired application. This password should be entered instead of your traditional Microsoft account password. It is important to note that recent clients like Office 2013 and later support modern authentication protocols and do not need app passwords if 2FA is active.

App-Specific Passwords for iCloud (Apple)
Apple requires the use of app-specific passwords to access iCloud data from third-party applications that were not developed by Apple itself, such as email or calendar clients. To generate them, sign in to appleid.apple.com with your Apple ID and password. In the “Sign-In and Security” section, select “App-Specific Passwords”. Click on “Generate an app-specific password” and enter a descriptive label (e.g., “Outlook on Windows”) to remember which service it is associated with. The system will create a 16-character password to copy and paste into the third-party app. In this case too, the password is displayed only once. Apple allows you to have up to 25 specific passwords active simultaneously and to revoke them individually at any time.
Management and Security in the European and Italian Context
In Europe, personal data protection is a central issue, regulated by the GDPR (General Data Protection Regulation). This regulation requires data controllers to adopt “adequate technical and organizational measures” to ensure data security. Password management falls fully within this obligation. The GDPR’s “risk-based” approach means that security measures must be commensurate with the risk. Using unique and complex passwords, enabling two-factor authentication, and employing app-specific passwords are all practices that demonstrate due diligence in account protection, in line with the principle of “accountability”. If you suspect someone might be accessing your accounts, it is crucial to know how to check recent activity.
Mediterranean culture, often based on relationships of trust, sometimes clashes with the need for a more rigorous and impersonal approach to digital security. However, the increasing digitalization of daily and professional life in Italy is accelerating awareness. Technological innovation, such as passkeys promising a passwordless future, sits alongside established traditions. In this scenario, educating users of all ages on tools like app passwords is a way to unite tradition (the account protected by the key) and innovation (advanced security tools), ensuring a safe transition towards a digital future.

Conclusions

App-specific passwords represent a fundamental link in the chain of personal and professional digital security. They offer a robust and pragmatic solution to the problem of having to link our main accounts, protected by two-factor authentication, with older applications that do not support modern security standards. Generating and using these one-time passwords for services like Google, Microsoft, and Apple is a simple operation that drastically reduces the risk of main account compromise. In a European context increasingly attentive to privacy and data protection under the aegis of the GDPR, adopting these best practices is no longer a choice, but a necessity. Protecting our digital identity requires a proactive approach that balances tradition and innovation, and app passwords are one of the most effective tools at our disposal to lock down our online life.
Frequently Asked Questions

An ‘app password’ is a special password, usually 16 digits long, created for an application or device that does not support modern access methods like 2-Step Verification. This one-time password allows the app to access your main account (such as Google, Apple, or Microsoft) without you having to enter your real password, which thus remains protected.
You should use an app password only when strictly necessary, i.e., when an older application or device does not support 2-Step Verification. Common examples include some desktop email clients, old video game consoles, or other devices that require access to an online account but are not updated with the latest security measures.
The procedure varies slightly depending on the service (Google, Apple, Microsoft). Generally, you need to access the security section of your main account, find the ‘App passwords’ option, and follow the instructions to generate a new one. The system will create a 16-digit password to copy and paste into the application requesting it.
Yes, they are considered a safe alternative when it is not possible to use 2-Step Verification. Since they are specific to a single application and different from your main password, they limit the damage in case of a security breach of that app. However, the safest option is always to use apps that support modern access via OAuth, such as ‘Sign in with Google’.
It’s not a problem. App passwords do not need to be memorized, as they are designed to be entered only once for each application. If for any reason you need to enter it again (for example, after reinstalling an app), you can simply go back to your account security settings and generate a new one, revoking the old one.
