Why your VPN keeps triggering extra security checks

Ever notice that websites keep asking you to verify your identity when you're using a VPN? Whether you're checking your bank account, signing into email or shopping online, those repeated security checks can get frustrating. Your VPN may be part of the reason.

A VPN changes the IP address websites see, which can sometimes trigger additional verification requests. Fortunately, a dedicated IP address may help reduce those interruptions while keeping your VPN protection enabled. Here's what you need to know.

YOUR BANK MAY STOP TEXTING YOU SIX-DIGIT CODES

First, let's set the record straight: A VPN generally does not interfere with how your passkeys or two-factor authentication codes work. Time-based authenticator codes are generated on your device and can work without an internet connection. Passkeys use cryptographic keys to verify your identity during a sign-in, while push notification approvals require a network connection. A VPN can usually work alongside all of these methods. What it does change is the public IP address websites see. When you connect through a VPN server, websites and apps see that server's IP address instead of your usual public IP address.

That's the whole point. But it's also why banks, email providers, and financial apps sometimes get nervous. These services use your IP address as one of many signals to decide whether a login looks legitimate. If you always log into your bank from roughly the same location and the same address, and suddenly your account is being accessed from a different city or a different country, the system flags it. Not because your VPN broke anything, but because from the apps point of view, someone new just walked in the door.

One common trigger is a VPN connection that uses shared IP addresses. Your public IP address may change when you reconnect or switch servers, although some VPN connections can keep the same address across multiple sessions. For a bank or workplace login portal that recognizes your usual login patterns, an unfamiliar IP address or location can raise a red flag.

The second trigger is shared IP addresses themselves. When hundreds of users connect through the same VPN server, they all appear to be coming from the same address. Websites and security systems recognize these addresses as VPN traffic and treat logins from them with extra suspicion. That means more CAPTCHAs, more verification steps, more temporary lockouts. Neither of these is a flaw in your VPN. It's doing exactly what it's supposed to do. But if you're regularly logging into sensitive accounts, those extra security checks can get frustrating fast.

One potential solution is a dedicated IP address. Instead of sharing an IP address with other VPN customers, you receive a
