How to Tell If Someone Is Trying to Hack My Account

Some security signals deserve more attention than ordinary spam.

Common warning signs include:

The FTC specifically identifies unauthorized login notifications, password or contact changes, and losing access to an account as signs that someone may have hacked it.

But the details matter.

An attempted login and a successful login are not the same event.

An attacker may only know your:

They may be guessing passwords or testing credentials obtained elsewhere.

Some login alerts are triggered even when authentication fails.

Read the message carefully.

Look for wording such as:

versus:

The first may mean an unsuccessful attempt.

The second deserves immediate review.

Email addresses and usernames are widely used as identifiers.

They can become known through:

Knowing your identifier does not automatically provide access.

Security should be designed with the assumption that usernames and email addresses may eventually become known.

The secrets and authentication methods behind them matter more.

This is especially important when passwords are reused.

Imagine your email and password were exposed through an old account several years ago.

If the same password still protects another account, someone can try the old credentials there.

CISA warns that malicious actors take advantage of passwords reused across systems, while NIST recommends unique passwords to reduce the ability to use credentials compromised elsewhere.

The service receiving the attack does not need to have suffered a breach.

The credential can come from somewhere completely different.

Many account-recovery systems allow someone to start a reset using an email address or username.

That means a person may be able to trigger a reset email without knowing your existing password.

The reset request alone usually does not mean they can complete the process.

The important question is whether they also control your recovery channel.

If your email account is secure, a reset message arriving in your inbox may simply show that someone knows the account identifier.

Do not automatically click the link in an unexpected reset message.

Open the official service separately and review activity there.

A code you did not request may mean someone reached a stage of authentication or recovery that requires additional verification.

Do not give the code to anyone.

Do not approve an unexpected MFA prompt.

A scammer might call or message you and claim:

The code may be precisely what prevents them from finishing the login.

Treat it like a temporary authentication secret.

Repeated MFA requests can occur when someone has enough information to reach the second step of authentication.

Never approve a prompt simply to make the notifications stop.

CISA recommends MFA broadly and explains that it significantly raises the difficulty of account takeover when passwords are compromised. It also recommends stronger phishing-resistant authentication where available.

Review the account's security dashboard.

If the account is email, also check:

The FTC recommends reviewing these settings after suspected email compromise because someone with access may create forwarding rules or make other changes designed to preserve access.

Location information is not always exact.

Internet providers, VPNs, corporate networks, mobile networks, and IP geolocation can make legitimate activity appear to come from another city or region.

Do not judge the alert solely by location.

Compare:

A completely unfamiliar device at an impossible time deserves more attention than a slightly unexpected city associated with your own phone.

Not automatically.

If you use a unique password, MFA is enabled, and there is no evidence the credential itself was exposed, a failed attempt may simply mean someone tried and failed.

If you change it, use a genuinely new password.

NIST recommends password managers because they can generate long, unique credentials and remove the temptation to reuse memorable passwords.

Attackers do not necessarily need to guess a complex password.

If that exact complex password was already exposed somewhere else, complexity no longer makes it secret.

A user creates a 20-character password.

That is good.

But they use it on six websites.

One of those websites experiences an exposure.

Now the same 20-character password can potentially be tested against the other five.

The issue is no longer password strength.

It is password reuse.

Unique credentials ensure that one breached service does not create a working key for another.

For accounts that still use passwords, password managers can solve one of the biggest practical problems: remembering unique credentials.

NIST highly recommends password managers and explains that they can generate and store unique passwords for individual accounts.

Secure the password manager itself carefully.

Use strong authentication and enable MFA if supported.

Because the manager protects many credentials, it deserves stronger protection than an ordinary low-value account.

Passkeys can substantially change this risk.

Traditional passwords can be:

Passkeys use unique cryptographic credentials associated with a legitimate service.

NIST explains that passkeys are phishing-resistant and do not create the same reusable-secret problem as passwords.

If an account you frequently worry about supports passkeys, consider adopting one.

Primary email accounts are particularly strong candidates.

Email is often the center of your digital identity.

It receives:

If someone gains access to it, they may be able to attack other accounts more easily.

The FTC warns that control of an email account can allow an attacker to receive password-reset links for other services.

Protect your email with:

This is one of the most important traps.

Someone is trying to hack your account.

The natural reaction is to click immediately.

That urgency may be the attack.

The FTC warns that phishing messages commonly claim there is suspicious activity or an account problem and then direct the victim to a fake website. It advises contacting the company independently instead of using unexpected links.

So if you receive a security alert:

An attacker should not be able to turn your concern about account security into the method they use to steal your password.

If you only opened a page and did not enter information, the appropriate response depends on what happened.

If you entered your password:

If you installed something or gave someone access to your device, take the device risk seriously.

The FTC recommends updating security software, running a scan, deleting identified threats, changing passwords, and enabling two-factor authentication when scammers may have gained access to a computer or phone.

In June 2026, the FTC also warned about fake CAPTCHA scams that can trick users into running commands that install malware capable of stealing login information; its advice included disconnecting, scanning the device, changing passwords, and enabling two-factor authentication from a different device if necessary.

Take control first.

If you can still sign in:

The FTC recommends these basic recovery actions after an account takeover.

If you cannot sign in, use the provider's official account-recovery process.

Do not pay strangers claiming they can recover the account for you through unofficial methods.

Account takeover can become an identity problem if the account contained sensitive information.

If you discover actual misuse involving personal information, IdentityTheft.gov can provide a recovery plan based on your circumstances. The FTC directs consumers there when stolen personal data may have been used for identity theft.

Again, do not assume every login attempt equals identity theft.

Escalate your response based on evidence.
