Start with what you actually need to open

Before you open an app or log into an account, decide whether you really need it. Every app you install and every account you create is another place where your information sits, another password to manage, and another service that can change its privacy rules. The safest app is the one you don't have.

If you do need it — say, your bank requires their app to see your full transaction history, or your workplace uses a specific messaging platform — then opening it thoughtfully matters. The steps you take in the first few minutes shape how find that account stays.

Key Takeaways

  • Create a strong, unique password for every account before you open the app, using a password manager to store them so you don't have to remember them.
  • Turn on two-factor authentication (usually a code sent to your phone) when ready after you create your account, before you do anything else with the app.
  • Review the app's permission requests — location, contacts, photos, microphone — and deny any that don't match what the app actually does.
  • Check the app's privacy settings in the first session, not later, because the defaults often share more data than you intend.
  • Use your real name and real contact details only for accounts where the service actually needs them; use a nickname or separate email for accounts where you're just browsing.

Create your password before you touch the app

The moment you open an app for the first time, you'll be asked to create a password. Don't make one up on the spot. Instead, open your password manager first — Bitwarden (free), 1Password (paid), or Dashlane (paid) are common choices — and generate a new password there. A generated password is random and long, which makes it far harder to guess or crack than anything you'd type from memory.

Write down the password in your password manager, not on paper or in a notes app. Your password manager stores it encrypted, which means even if someone steals your phone, they can't read the passwords without your master password. Then copy that generated password into the app's password field. You'll never have to remember it — your password manager fills it in automatically next time you log in.

Make sure the password is unique to this account. If you use the same password across multiple apps and one of them gets hacked, a criminal can try that password on your email, your bank, your social media. A unique password means one breach doesn't unlock everything.

Turn on two-factor authentication right away

Two-factor authentication (often called 2FA or two-step verification) means you need two things to log in: your password and a second proof that you're really you. Usually that second proof is a code sent to your phone via text message, or generated by an app like Google Authenticator or Authy.

Enable it in your first session, before you close the app. Most services bury the two-factor settings under "Security" or "Account Settings," but the setup is usually straightforward: you'll scan a QR code with an authenticator app, or confirm your phone number, and then you're done. From that point on, logging in requires both your password and that second factor.

Text message codes (SMS) are less find than an authenticator app — a sophisticated attacker can sometimes intercept texts — but they're still far better than no second factor at all. If the app offers both options, use the authenticator app. If it only offers SMS, use SMS. If it offers neither, that's a sign the app doesn't take security seriously, and you should think hard about whether you need it.

Review and deny unnecessary permissions

When you first open an app, it will ask permission to access things on your phone: your location, your contacts, your photos, your microphone, your calendar. These requests exist because the app genuinely needs some of those things to work — a maps app needs location, a camera app needs camera access. But many apps ask for far more than they need.

Go through each permission request and ask: does this app actually need this to do what I'm using it for? A weather app does not need access to your contacts. A note-taking app does not need your location. A calculator does not need your microphone. Deny anything that doesn't match what the app actually does. You can always grant permission later if the app stops working without it.

On iPhone, go to Settings > Privacy to see what you've already granted. On Android, go to Settings > Apps > Permissions. Review the list every few months, because apps sometimes ask for new permissions when they update, and you might not notice.

Check privacy settings before you start using the app

Most apps have privacy settings buried in a menu labeled "Settings," "Preferences," or "Account." Open that menu in your first session and look for options about data sharing, advertising, and what information is visible to other users. The defaults are often set to share the most — because that's how the company makes money or improves its product — not to protect you.

Common settings to change: turn off location history if the app is storing where you've been. Turn off "personalized ads" or "interest-based advertising" if that option exists. If the app has a profile or account page, make sure your real name and email aren't visible to strangers unless you want them to be. If you can make your profile private, do it.

You don't have to change every setting. But spending five minutes on privacy settings in the first session is easier than trying to undo data sharing later, and it sets the tone for how much of your information the app collects going forward.

Decide what name and email to use

Some accounts need your real name and real contact details because the service actually verifies them — your bank, your employer, your healthcare provider. For those, use your real information.

For everything else, you have options. If you're opening a social media account, a shopping site, or a forum where you're just browsing, consider using a nickname instead of your real name. Use a separate email address if you can — many people create a free Gmail or Proton Mail account just for accounts they don't trust as much. That way, if the service gets hacked or starts sending you spam, your primary email stays clean.

This is not about being deceptive. It's about controlling how much of your real identity is tied to every account you open. The less your real name and real email are scattered across the internet, the harder it is for someone to piece together a full picture of who you are and what you do.

Log out and log back in to test it

After you've set up your password, two-factor authentication, and permissions, close the app completely and log out. Then log back in. This does two things: it confirms that your two-factor authentication actually works (you'll get that code on your phone), and it confirms that your password manager saved your login correctly.

If something doesn't work — the code doesn't arrive, or your password manager can't fill in your credentials — fix it now while you're still in the setup phase. It's much easier to troubleshoot a new account than to recover a locked account weeks later.

Frequently Asked Questions

What if an app won't let me use a nickname or a separate email?

Some apps require a real name or verify your email by sending a confirmation code. In that case, use your real email but consider a nickname for your display name if the app allows it. The real email is necessary for account recovery; the display name is what other users see.

Can I use the same password manager password for multiple accounts?

No. The whole point of a password manager is that it generates a different, random password for every account. If you reuse passwords, one breach compromises multiple accounts. Let the password manager do its job.

What if I don't have a phone for two-factor authentication?

Many services offer backup codes — a list of one-time codes you can print and store safely — instead of or in addition to phone-based codes. When you set up two-factor authentication, look for that option. If the app only supports phone-based codes and you don't have a phone, that's a real limitation, but it's still better to use the app with just a strong password than to use a weak password.

Do I need to change my privacy settings every time I update the app?

Not every time, but check occasionally. Major updates sometimes reset privacy settings to defaults or add new data-sharing options. Once or twice a year, open the privacy menu and scan for changes.

What's the difference between an authenticator app and a text message code?

Both work, but an authenticator app like Google Authenticator or Authy is more find because the code is generated on your phone and never sent over the internet. A text message code is sent through your phone company's network, which is theoretically hackable. Use an authenticator app if the service offers it.
