How Often Should You Change Your Password? – Best Ways To Protect Your Privacy in 2022

How often should you change your password? This question has been around for as long as there have been passwords. Years ago, you may have had 5-10 passwords. Now, you likely have over 100. So, how often should you change your passwords?

The Threat

What would happen if someone got one of your passwords?

  1. They could do immediate damage.
  2. They could spy on you for weeks, months, or years.

What kind of damage might they do? They might transfer money out of one of your bank accounts, send spam emails from your account, or post harmful content to your social media accounts.

What kind of spying might they do? They might monitor your financial activity, or monitor your conversations by email or social media.

How would someone get your password?

  • Data breach (it’s stolen from an organization)
  • Guess it (try personal details such as names, dates, etc.)
  • Observe it (watch you enter it, see it written)
  • Trick you (phishing, etc.)
  • You share it (with family or friends)

How Often Should You Change Your Password To Increase Your Security

You’ve probably heard that you should regularly change your passwords, in case someone gets ahold of them. The idea is that if someone is using one of your passwords, and you change it, that will cut off their access.

This has led many organizations to require people to change their passwords on a schedule, such as every 30, 60, or 90 days. Unfortunately, this has led to poor password practices:

  • Creating weak passwords
  • Using the same password for multiple accounts
  • Using predictable passwords

As data breaches have become more common, these issues have become more serious. So, in recent years, industry experts have reversed the advice to regularly change passwords.

Verifiers SHOULD NOT require memorized secrets to be changed arbitrarily (e.g., periodically). However, verifiers SHALL force a change if there is evidence of compromise of the authenticator.

NIST Special Publication 800-63B, Digital Identity Guidelines (

Periodic password expiration is a defense only against the probability that a password (or hash) will be stolen during its validity interval and will be used by an unauthorized entity. If a password is never stolen, there’s no need to expire it. And if you have evidence that a password has been stolen, you would presumably act immediately rather than wait for expiration to fix the problem.

… the greatest risk to your password is no longer cracking, but password harvesting. Cybercriminals infect your computer with keystroke loggers, data harvesting via phishing websites, people sharing or reusing passwords, social engineering attacks over the phone, SMS texting, or a number of other methods.

Basically, since the threat model has changed, if your password is compromised, it will almost certainly be collected in seconds, not months. And when the bad guy gets your password, they are not going to wait the required ’90 days’, they are going to leverage it within hours. So by the time you get around to changing your passwords the bad guys are long gone. Regular password changing only makes you feel more secure. It does not do anything to actually secure you.

SANS Institute (

Forcing password expiry carries no real benefits because:
• the user is likely to choose new passwords that are only minor variations of the old
• stolen passwords are generally exploited immediately
• resetting the password gives you no information about whether a compromise has occurred
• an attacker with access to the account will probably also receive the request to reset the password
• if compromised via insecure storage, the attacker will be able to find the new password in the same place

National Cyber Security Centre [UK] (

As mentioned, it’s more likely that someone who gets your password will do immediate damage than secretly spy on you. And if they try to do immediate damage, you’ll likely notice and be able to respond. So, it’s not necessary to regularly change your passwords.

Now, changing your passwords doesn’t hurt (other than the time you spend), but it does little to increase security.

If your passwords are strong, and especially if you have two-factor authentication enabled, don’t feel that you need to periodically change your passwords.

However, this doesn’t mean that you never need to change another password in your life. Let’s look at several situations in which you should change your password.

After a Data Breach

When you’re informed that your data was a part of a data breach, change your password immediately.

If you used that same password for any other accounts, change those immediately, too. When hackers get breached passwords, they try them all over the Internet, just to see what else they’ll unlock. This is called credential-stuffing. So, make sure that you use unique passwords for all accounts.

The password manager LastPass automatically informs you when your email address has been exposed in a data breach, and which breach it was. That way, you know which password you should change.

After Being Hacked

When one of your accounts is hacked, such as an email account or social media account, change your password immediately.

When one of your devices (computer, phone, tablet, etc.) is hacked, or gets malware, change the password of the device, and of any accounts that were accessible from that device.

After Fraud or Theft

When you’re the victim of fraud or theft that’s performed digitally, change the password of the financial institution.

Also, in the case of a fraudulent purchase, change the password of any accounts with the merchant (seller) that sold the items. For example, if the fraudulent purchases were from Amazon, change the password of your Amazon account.

To Change a Default Password

Unfortunately, many devices come with default passwords, such as wireless routers and smart devices, aka Internet of Things (IoT) devices. These often have a password printed on the device or in the paperwork that came with the device. These passwords are readily available online, so hackers can easily use them.

When you have a device (or software) that comes with a default password, change the password immediately.

After a Password is Sent via an Insecure Channel

There are secure ways to send passwords and insecure ways. If a password is sent over an insecure channel, such as SMS/text or email, or over public Wi-Fi to an insecure website (HTTP rather than HTTPS), that password could be captured.

Maybe you never send a password over an insecure channel, but you may receive a password over an insecure channel. For example, when I create a new account, occasionally the company emails me my password. This is infuriating because it’s insecure.

When a password is sent by you or to you over an insecure channel, change your password as soon as possible in a secure way, using your device on a trusted network.

After Entering the Password on a Public Device

You never know what malware or hardware keyloggers may be running on a public device, such as a computer or tablet at an airport, library, or Internet café. So, you can’t trust them and should avoid them whenever possible.

If you’re ever required to enter a password on such an untrusted device, change your password as soon as possible in a secure way, using your device on a trusted network.

To Change a Weak Password

When you realize that one of your passwords is weak, change the password immediately.

To Stop Sharing an Account

When you want to stop sharing an account with family or friends, change the password.

How to Change Passwords

When you create a new password, make sure it’s a strong password (long, complex, and random).

I mentioned earlier that you should change passwords using your device on a trusted network.

Some accounts give you the option to log out all other devices and users who are logged into the account. You should do this to immediately block access to your account. Otherwise, someone may be able to access your account for some time even after you change the password.

When you change a password, also change your security questions, PIN(s), and any other details that a person could use to gain access to your account. See if your account offers any additional forms of security that you can activate, such as two-factor authentication.

How are you going to create and remember all these passwords? A secure and convenient tool is the password manager. I recommend LastPass.

Why Using A Password Manager Better Than Frequent Password Changes?

Using a password manager can help you protect your online information better than frequent changes to your passwords because you can use one stand-alone master password (or passphrase) to get access and you don’t have to re-enter your password each time you log in to any of your online accounts. This saves time and most password managers have better security than most sites you use.

Another obvious reason why password managers are better is remembering lots of passwords is difficult. You need to get them right every time-regularly, or you’ll get locked out of all the services you use. Having a password manager will simplify site logins significantly.

Frequently Asked Questions

How often should I change my passwords?

Changing passwords periodically is a good way to keep them safe from hackers. Security experts recommend you change your password every quarter or every three months. Multi-factor authentication is one way you can beef up the security of those passwords along with frequent password changes.

Is it good to change passwords regularly?

Yes. But not too often, since the more passwords you have, the more likely it is that you’ll forget them. One way to avoid forgetting passwords is to make use of a password manager like LastPass.

Where should I store my passwords?

You can safely store passwords on LastPass. It is a free password manager that generates strong passwords and safely stores them in its vault to prevent unauthorized access. It’s available on desktop, as well as smart devices running Android or iOS!

Should I write down my passwords?

It is not recommended. Although writing passwords down on paper or a sticky note might seem like a simple way to keep track of your passwords, doing this only makes you more vulnerable to theft. Also, those who write down passwords are more likely to use the same password again. Password reuse is the worst thing you can do when it comes to keeping accounts secure and protecting yourself from hackers!

  1. Don’t think that you need to change all your passwords regularly, though doing frequent password changes doesn’t hurt.
  2. Change a password if any of the following occurs:
    1. You’re a victim of a data breach
    2. You get hacked
    3. You’re a victim of fraud or theft
    4. You set up a device that has a default password
    5. Your password is sent over an insecure channel
