Password security: mistakes to avoid

Passwords are essential for protecting our digital devices. If we do not use them correctly, we put our data at risk. It is like leaving the door to your house unlocked.

In this article, we will discuss common mistakes in password management. We will give you practical advice based on best practices. Our sources include the Polizia Postale and experts such as Troy Hunt.

We will discuss weak passwords, why we should not reuse them and the importance of two-factor authentication. We will also explore unsafe password sharing and storage. We will also look at how theft and tools such as password managers can help us.

Our aim is to show you the importance of good password security. We want to give you advice that is easy to follow in your everyday life. This will help you reduce the risk of unauthorised access and identity theft.

Why password security matters

Protecting your credentials is essential for safeguarding your digital identity, bank accounts and cloud services. Understanding the importance of having secure passwords helps prevent financial losses and identity theft. It also protects your business or personal accounts, such as those with Google and Apple, from unauthorised access.

Passwords as the first line of defence

Passwords are the first line of defence between you and your sensitive data. If passwords are weak, an attacker can easily access email, online banking and cloud storage within seconds.

Consequences of weak or compromised passwords

A weak password can lead to identity theft and banking fraud. If an account is compromised, your personal and professional information may be exposed. Anyone who uses the same password for several services risks having all their accounts compromised.

Relevant data and statistics

Simple sequences are very common in public lists of compromised passwords. In 2024, the most widely used password in Italy was once again “123456”. Security reports show that terms such as “password”, “qwerty” and “12345678” are often among the most widely used.

The Polizia Postale advises against using family members’ names, dates of birth and dictionary words. It advocates using complex passwords that are unique to each account. This improves security and helps make passwords more secure.

Using weak passwords: common mistakes and solutions

Many accounts are vulnerable because they use passwords that are easy to guess. Here we look at the most common mistakes and how to avoid problems. We offer tips for having secure passwords without making life complicated.

Which passwords to avoid

Avoid sequences such as 123456 and qwerty. Common words such as password are not secure. Family members’ names and dates of birth are also easy to guess.

How to create complex passwords

A good password has at least 12 characters. Using more is better. A good mix of letters, numbers and symbols makes a password more secure.

Examples of poorly chosen passwords and secure alternatives

An example of a weak password is T3L3VI510N3. A more secure password is rtuoiry55TyUo77#. Long, non-obvious phrases are also a good option.

• Mistake: 1q2w3e4r — Alternative: rtuoiry55TyUo77#
• Mistake: name+year (Mario1985) — Alternative: a long phrase with symbols and numbers
• Mistake: password, iloveyou — Alternative: a long, unique phrase

To create secure passwords, use reliable generators. Password managers help you manage complex passwords. Follow rules on length and variety to reduce the risk.

Password reuse and password management

Reusing passwords is very dangerous for online security. A single data breach on sites such as LinkedIn or Yahoo can lead to automated login attempts on other sites. It is important to understand how the attack works and find solutions for managing passwords.

Why reuse is dangerous

When an email and password combination is exposed, attackers use automated tools to try it on dozens of services. This method exploits the fact that many people reuse the same credentials for both low-value and high-value accounts. The result can be access to email inboxes, bank accounts and social media profiles.

Tools such as Shard and other bots make it easier to check credentials in bulk. For this reason, avoiding password reuse is the first line of defence for improving personal and business password security.

Tools for secure password management

A password manager lets you store unique, complex credentials behind a master password. Experts such as Troy Hunt recommend reliable solutions for secure synchronisation and automatic generation.

Some of the best-known tools include LastPass, 1Password, Bitwarden and KeePass. Each offers different features: password generation, autofill and breach checks. Choosing a robust tool simplifies password management and helps improve password security across multiple services.

Practical strategies for keeping passwords different

A useful approach is to classify accounts by importance: bank accounts, email and work accounts require unique passwords and regular changes. For less critical accounts, simpler variations can be used while still keeping each one unique.

Updating sensitive credentials every 3-6 months is recommended. Using random phrases or generators built into the password manager helps create passwords that can only be remembered through the manager.

Problem	Risk	Practical solution
Password reuse	Credential stuffing and multiple logins	Use a password manager and create unique passwords
Weak passwords	Fast cracking using dictionaries	Generate complex passwords or random phrases
Failure to rotate passwords	Compromised credentials kept for a long time	Update every 3-6 months for critical accounts
Lack of secure recovery	Password resets that attackers can exploit	Protect recovery email addresses and phone numbers, enable 2FA

Ignoring two-factor authentication and other additional protections

Not using security tools can put your accounts at risk. Two-factor authentication greatly reduces the chances of unauthorised access. But many important services such as Gmail and banking apps do not use it enough.

What two-factor authentication (2FA) is and why you should enable it

2FA adds a second step beyond the password. This step can be a code sent by SMS, an app such as Google Authenticator, or a hardware key. Enabling it greatly reduces the risk even if your password is stolen.

For email, banks and businesses, enabling 2FA is essential. It helps protect passwords and makes risks easier to manage.

Other protection measures beyond passwords

Hardware keys based on FIDO2/WebAuthn offer greater security. Checking active sessions and restricting access from suspicious IP addresses helps detect unusual activity.

Enabling security alerts from services and browsers is useful. These notifications warn you about new connections or password changes. These practices improve security without complicating everyday life.

How to combine 2FA with effective use of a password manager

A password manager such as Bitwarden or 1Password keeps passwords secure. It can also store 2FA codes securely. Keeping backups of 2FA codes helps prevent you from losing access if you change devices.

Do not send codes by email or SMS, to keep them protected. For high-risk accounts, consider hardware keys alongside a password manager. These tips improve account security.

Storing and sharing passwords: mistakes to avoid

Managing credentials requires care and secure habits. This section explains why it is important to handle password storage and sharing carefully. Doing so reduces risks.

The dangers of storing passwords in plain text

Writing passwords on sticky notes or in unprotected files is dangerous. An infected device or unauthorised access makes them easy to read.

Sending passwords by email or SMS is just as risky. The Polizia Postale states that these channels are not secure. It is better to use tools with end-to-end encryption.

Sharing passwords: when it is risky and secure alternatives

Sharing credentials with others increases the risk. Even when you trust someone, there are always risks of loss or unintentional disclosure.

Password managers such as 1Password and LastPass offer encrypted sharing. For businesses, it is better to use separate accounts or temporary access.

Physical and digital protection of credentials

Password security starts with devices. Using BitLocker on Windows or FileVault on macOS protects data. Automatic screen locking helps limit unwanted physical access.

To defend against keyloggers, keeping systems updated and using antivirus software is essential. Avoiding typing passwords in crowded places is another tip. For effective protection, choose solutions that combine encryption, strong authentication and protected backups.

For secure password management, use a password manager. Do not reuse credentials, and set up temporary access whenever possible. Regularly review the permissions you have granted.

How passwords are stolen: techniques and how to protect yourself

Understanding how passwords are stolen helps prevent theft. Here we will discuss the most common techniques. We will also look at tools for checking whether passwords have been compromised and how to reduce the risk.

The most common techniques for stealing passwords

Phishing is a major threat: fake emails or websites ask for credentials. Social engineering uses information from social media to guess passwords.

Brute-force attacks and tools such as John the Ripper try many combinations. Credential stuffing uses credentials stolen from other sites.

Keyloggers record keystrokes. Interception over unsecured Wi-Fi reads data in transit. Shoulder surfing involves watching someone type their password in public.

Public tools for checking for compromised credentials

Services such as haveibeenpwned check whether an email address has been compromised. Modern browsers warn you if a password has been stolen.

Extensions such as PassProtect for Chrome warn you if your password has been stolen. These tools help check whether passwords have been compromised.

Good practices to reduce the risk of theft

Changing credentials after a breach is important. Using a password manager helps create secure passwords.

Enabling two-factor authentication protects important services. Updating the operating system and applications protects against malware.

Do not enter passwords on public Wi-Fi or send credentials by email or SMS. Training on phishing and social engineering helps you recognise theft attempts.

• Regularly check haveibeenpwned or tools built into your browser.
• Use long passwords with a mix of characters and random phrases.
• Enable 2FA and use a reliable password manager.
• Keep software and antivirus updated.
• Do not share credentials over insecure channels.

Conclusion

Password security is very important. You should avoid weak passwords and not use them more than once. Using at least 12 characters, with letters, numbers and symbols, helps protect data.

Using a password manager and two-factor authentication is useful. Checking services such as Have I Been Pwned and changing compromised passwords is essential. These steps improve password security.

Following guidance from the Polizia Postale and experts helps improve protection. Small changes to everyday habits and the use of suitable tools make passwords more secure. This improves the protection of login credentials.
