Criminals no longer need to steal your password to take over your online accounts. Attackers have found several ways around traditional password protection, including hijacking active login sessions, approving sign-ins through repeated prompts, taking control of phone numbers, deploying malware that harvests device data and abusing permissions granted to connected applications. Passwords remain important, but they are only one part of the system that protects an identity.
The first threat involves active sessions. When you sign in to a website, the service often creates a session that confirms you have already verified your identity. Browsers and apps may keep that session alive so you do not have to re-enter your password every few minutes. Criminals can sometimes steal the digital tokens or cookies tied to those sessions. If the service accepts the stolen information, an attacker can gain access without entering a password or completing another verification step. To guard against this, users should review the devices and active sessions connected to their accounts, sign out of anything unfamiliar and check for suspicious login activity. If unauthorized access is suspected, the password should be changed from a trusted device and other sessions revoked where the service allows. Removing a device from an account list does not always end an active login session.
A second threat targets the phone number itself. Phone numbers are frequently linked to email, banking, payment and social media accounts. Criminals may try to persuade a mobile carrier to transfer a victim's number to a SIM card or eSIM they control. If the transfer succeeds, they can receive calls and text messages meant for the victim, including some account verification codes. Warning signs include a sudden loss of cellular service when there is no known local outage, an unexpected carrier notice about a device change, or a password-reset message the user did not request. Users can ask their carrier about an account security PIN, a number transfer lock or port-out protection, though these protections vary by carrier. For sensitive accounts, a passkey, security key or authenticator app is preferable, since those codes do not depend on the phone number. If text messages are the only second factor available, they should stay enabled, because they still offer more protection than a password alone.
Multifactor authentication adds a valuable layer of security, but criminals sometimes target the person receiving the request rather than the login itself. One tactic is known as MFA fatigue, or push bombing. An attacker who can trigger authentication requests repeatedly sends approval notifications in the hope that the victim eventually taps «Approve» to make them stop. Criminals may also pose as technical support or a financial institution and ask people to read aloud a one-time security code. The guidance is direct: never approve a login you did not initiate, never share a verification code with someone who contacts you unexpectedly, deny repeated prompts, and check the account through its official website or app. If a password may be compromised, change it. Where available, phishing-resistant options such as passkeys or security keys offer stronger protection, and app-based approvals that require number matching can help prevent accidental approvals.
Infostealers represent a further risk. These malicious programs are designed to collect information from a device, which can include browser-stored passwords, session cookies, payment details and other sensitive data. They can spread through fake software updates, pirated applications, suspicious email attachments, malicious advertisements and compromised browser extensions. Because some malware runs quietly, victims may notice nothing unusual at first. Protection starts with keeping the operating system, browser and security software current, avoiding downloads from unfamiliar websites and reviewing browser extensions regularly. If an infection is suspected, users should secure important accounts from a separate, trusted device, run a scan with reputable antivirus software and remove suspicious programs. For a serious infection, professional help or reinstalling the operating system may be necessary, and users should avoid signing back into sensitive accounts until the device is confirmed secure.
The final threat requires no password theft or device infection at all. Criminals may trick people into granting a connected application permission to access their information. A fake productivity tool, for example, might request access to read email, view contacts or manage files in cloud storage. Once that permission is approved, the attacker can work through the authorized app rather than the user's login. Taken together, the six threats show that account security now depends on sessions, phone numbers, verification prompts, devices and third-party permissions, not just on a password. Reviewing active sessions, securing the mobile number, treating unexpected prompts with suspicion, keeping devices clean and auditing app permissions are the practical steps that can close the gaps criminals are exploiting.
