In short

  • You enable two-factor authentication on Instagram via Settings, Accounts Center, and the Password and Security option.
  • Instagram offers an authentication app, SMS, and WhatsApp, and recommends the authentication app itself.
  • Save your backup codes right after enabling it, otherwise you might lose access if you lose your phone.
  • In Accounts Center, regularly check where you're logged in and log out any unknown devices.
  • Do not share your password or authentication codes with anyone, not even with apps or services that ask for them.

You enable two-factor authentication on Instagram in the app via Settings, Accounts Center, Password and Security, and Two-factor authentication. Select your account and method (authentication app, SMS, or WhatsApp) and complete the setup according to the on-screen instructions. Right after that, save your backup codes so you can access your account even without your phone.

What is two-factor authentication and why should you enable it?

Two-factor authentication (in English: two-factor authentication, abbreviated as 2FA) is a security measure where you enter a one-time code in addition to your password. Instagram asks for it when someone tries to sign in from a device it doesn't recognize.

Anyone who discovers your password, for example from a data breach or phishing site, won't be able to access your account without the code. Instagram in its tips on securing your account two-factor authentication as the most effective step to protect your account from hackers (as of November 2026).

It's prevention. If you're already losing access to your account or have lost it, follow the guide what to do if your Instagram account has been hacked.

How to enable two-factor authentication on Instagram step by step?

You can find the settings in Accounts Center, a common place for Meta account settings. The procedure according to Instagram Help Center articles on two-factor authentication (as of November 2026):

  1. Open the Instagram app and go to your profile.
  2. Tap the menu (More) and select Settings.
  3. Tap View more in Accounts Center.
  4. Select Password and Security.
  5. Tap Two-factor authentication and select the account you want to secure.
  6. Select the method and follow the on-screen instructions.
  7. After completion, save your backup codes (the procedure is below).

Item names may vary slightly in the Czech version of the app, and Meta changes the interface from time to time. If you can't find an item, use the search in Settings and enter "two-factor" or "security".

Which authentication method should you choose?

Instagram offers three methods: authentication app, SMS, and WhatsApp. The help designates the authentication app as the recommended method (as of November 2026).

MethodHow it worksThings to consider
Authentication appAn app on your phone (for example, Google Authenticator or Duo Mobile) generates login codes.Recommended method. According to the help, it can only be enabled in the Instagram app for Android or iPhone.
SMSInstagram will send a code to your phone number.Simple setup, but depends on message delivery and keeping the number under your control.
WhatsAppThe code will come via WhatsApp.According to the help, you must first enable SMS verification, and then WhatsApp works as an additional method of code delivery.

How to set up an authenticator app?

  1. Install an authenticator app from the official app store (App Store or Google Play).
  2. In Instagram settings, select Authenticator App as your two-factor verification method.
  3. Instagram will offer a connection with the app on your phone, or a key or QR code that you add to the authenticator app.
  4. The authenticator app will start displaying a six-digit code that changes regularly. Enter it back into Instagram.
  5. This activates the method. At your next sign-in from an unknown device, you will enter the current code from the app.

And a security key?

A security key is a small physical device (such as a USB key) that you use to confirm your sign-in by connecting or tapping it. Facebook's help lists it as one of the two-factor verification methods alongside an authenticator app and SMS (Facebook's help on two-factor verification). Instagram's help does not list it among the methods for Instagram as of November 2026. To verify whether you can use it for your Instagram account, check directly in Account Center under additional methods.

Where to find backup codes and how to save them?

Backup codes are one-time codes that you use to sign in if your regular verification code doesn't arrive or you don't have your phone handy. Without them, you may lose access to your account if you lose or replace your phone.

Follow the instructions in Instagram's help on backup codes (as of November 2026):

  1. Open Settings and go to Account Center.
  2. Select Password and Security, then Two-Factor Authentication.
  3. Select your account.
  4. Tap Additional Methods and then Backup Codes.

You can only view the codes when you are signed in. Therefore, save them immediately after enabling verification. Help recommends copying them, taking a screenshot, or saving them in another secure location.

  • Save them outside the phone you use for verification, for example printed at home or in a password manager.
  • Do not send them by email or in chat, not even to yourself.
  • If you use the codes or suspect someone has seen them, generate new ones by selecting Get New Codes. The old ones will then become invalid.

How to check where you are signed into Instagram?

You can find a list of devices with active sign-ins in Account Center under Password and Security in the Where You're Signed In section. You can remotely sign out unknown or old devices from there.

According to Meta's help on signing out from another device each item contains the date, time, location, and device type (as of November 2026). Steps:

  1. In Account Center, open Password and Security.
  2. Tap Where You're Signed In and select your account.
  3. Go through the list and select Select Device to Sign Out.
  4. Mark devices you don't recognize or no longer use (or Select All), and confirm the sign-out.

If you find a device you don't recognize, change your password after signing out. The location in the list is usually approximate, so a different city alone doesn't necessarily mean unauthorized access. The key factors are the device type and time.

Trusted Devices

You can mark your personal phone or computer as trusted so Instagram won't ask you for a code every time you sign in. Instagram's help explicitly warns you not to mark public or shared devices that people you don't know have access to as trusted.

What else protects your account besides two-factor verification?

Two-factor verification is the foundation, but it is not enough if you have a weak password or an unsecured email. Instagram recommends these steps in its security tips (as of November 2026):

  • A strong and unique password. A combination of at least six numbers, letters, and special characters, without your date of birth or name. Use a different password for each account, ideally in a password manager.
  • A secure email. Whoever has access to your email will likely also gain access to your Instagram. Enable two-factor authentication for your email account as well.
  • Caution with third-party applications. Whoever knows your login credentials has full access to the account. Do not log in to Instagram through applications you don't trust.
  • Log out on unfamiliar devices. On a shared computer, do not check 'Remember me' and log out after use.

Why not share your password and codes with anyone?

Your password and verification code are the only things separating a stranger from your account. Whoever knows them can change your email, phone number and password, and two-factor authentication won't stop them at that point.

Scammers therefore often don't ask for the password directly, but rather 'just the code you just received'. They impersonate Instagram support, a friend, a brand offering collaboration, or a service promising your profile growth. As soon as you type in the code, they log in.

  • Don't send the verification code to anyone, even if the message appears to be from Instagram. If you're unsure, open the app yourself and check your account status in Settings.
  • To increase your followers or likes, no one needs your password. More details in the article why you should never share your password even when buying followers.
  • Other warning signs, such as requests to log in through third-party pages or promises of unrealistic results, are described in the text how to recognise a risky seller.

If you've already given someone your code or password, immediately change your password, log out other devices in Account Center, and check the email and phone number in your account. If someone threatens your account or demands money from you, contact the Czech Police.

When paid promotion makes sense and when it does not?

Paid promotion has nothing to do with account security, and you should have two-factor authentication enabled in any case. If you're considering a followers package, know that Meta's rules on inauthentic behavior prohibit artificially increasing content popularity and follower count, so account or reach restrictions cannot be ruled out. We point this out in our terms of service (Art. 3.3)Purchased interactions will not replace content, will not guarantee audience interest or sales, will not help meet monetization or verification requirements, and may worsen the ratio of reactions to followers.

It may make sense as initial social proof for a new profile that already has good content, or as a supplement to a specific campaign alongside your own work. It does not make sense for an account without content, for an account with warnings or restrictions, or when you're expecting genuine engagement from people.

Frequently asked questions

What to do if you lose your phone when you have two-factor authentication enabled on Instagram?

Sign in using one of the backup codes you saved when you enabled authentication. Each code will let you into your account even without your phone. After logging in, set up authentication for your new phone in Accounts Center and generate new backup codes. If you don't have the codes and can't sign in, follow Instagram's help for account recovery at instagram.com/hacked.

Is an authentication app better, or SMS?

Instagram's help designates the authentication app as the recommended method (as of November 2026). The code is generated directly on your phone, so it doesn't depend on SMS delivery or signal. SMS is easier to set up and works well as a backup option. It makes sense to have the app enabled and to have backup codes saved.

Can I turn off two-factor authentication on Instagram again?

Yes. The procedure is the same as when enabling it: Settings, Accounts Center, Password and Security, Two-factor authentication, select your account, and turn off the chosen method. However, turning it off means your account is protected only by your password again. If authentication bothers you because you have to enter the code frequently, mark your personal phone as a trusted device instead.

Does a profile promotion service need my password or authentication code?

No one needs your password or two-factor authentication code to increase your followers or likes. Instagram warns in its help that anyone who knows your login credentials has full access to your account. If someone asks for your password or code, whether it's a seller, 'support,' or an alleged partner, take it as a warning sign and don't share your information.

Do I have to enter the code every time I log in to Instagram?

No. Instagram requires the code when attempting to sign in from a device it doesn't recognize. You can mark your personal phone or computer as a trusted device, and you won't have to enter the code on it during future sign-ins. However, Instagram's help warns you not to mark public or shared devices as trusted, especially those that people you don't know have access to.
