IP masking explained: what you need to know

Why do I need to mask my IP?

Your IP address is like your home address online – it tells websites where you’re connecting from. If you don’t mask it, you could run into trouble:

• Websites tracking you: sites remember your IP and can link your activity across accounts
• Account bans: if platforms detect multiple accounts from the same IP, they might suspend them

By using a proxy, VPN, or mobile network, you keep your real IP hidden, making it harder for websites to detect or block you.

How can I mask my IP?

Staying off the radar online is key. But how do you do that? You’ve got a few options:

• Proxies: think of them as disguises for your internet connection. Each one gives you a different “mask” (IP address) so websites don’t catch on
• VPNs: like a secret tunnel for your data, but the catch? You only get one disguise at a time, which isn’t great for multi-accounting
• 4G/5G mobile networks: you get a new IP when you restart your hotspot, but it’s random and harder to control

For online privacy, proxies are hands-down the best bet – you can give each profile its own IP, making them look like completely different users.

Can I use 3rd-party apps with Multilogin?

Certain third-party apps can interfere with Multilogin, causing issues with browser profiles and connectivity. These include:

• 🦠 Antivirus software
• 🔥 Firewalls
• 🌍 VPN apps
• ⚒️ Proxy tools (e.g., Proxifier, SocksEscort) 

To prevent conflicts, we recommend uninstalling these apps. If that’s not an option, try disabling them or whitelisting Multilogin and its folders in their settings.

Can I use a VPN to mask my IP?

Only OpenVPN protocol is supported – other VPN protocols may cause issues.

Important limitation: a VPN assigns a single IP address to your entire system. This means that:

• ❌ You can’t use different IPs for multiple browser profiles at the same time
• ✅ Instead, you’ll need to work one profile at a time and change the IP before opening a new profile

Proxies explained: your top questions

Why should I use a proxy?

While Multilogin masks all essential browser fingerprints, a proxy ensures your real IP and IP-dependent parameters stay hidden – keeping you undetected.

To stay safe, use a different proxy for each browser profile where you manage a separate account.

But not all proxies are created equal! Low-quality proxies can:

• 🔍 Expose your real IP
• 🚫 End up on blacklists
• ⚠️ Trigger website restrictions or bans 

Are built-in Multilogin proxies good enough?

Absolutely! Multilogin’s built-in proxy service is the best option for seamless, reliable, and high-quality IP masking. Why? Because it gives you 5 million premium residential IPs with unbeatable benefits:

• Sticky IPs: keep the same IP for a set duration to maintain account consistency
• Bandwidth rollover: no wasted data, your unused bandwidth carries over
• Strict quality control: only the best IPs make the cut, ensuring high anonymity and security
• Global coverage: 150+ countries, so you can access any region effortlessly

If you want a hassle-free, top-tier proxy experience with zero setup required, Multilogin’s built-in proxies are the ultimate choice.

Do I need a new proxy for each browser profile?

If you are using Multilogin for multiple accounts – then yes, it is better to have a different IP (proxy) for each browser profile to make sure they have different IP-dependent data.

If you use a 4G hotspot, you need to restart it to get a new IP. 

How do I know my proxy type?

You can check it with your proxy provider or find out on your own. 

To see if your proxy is residential or datacenter, head over to browserleaks.com/ip and look for the "Usage Type" parameter. Alternatively, see the "ISP" parameter right above and google its name:

• If the ISP is a web hosting company, you most likely have a datacenter proxy
• If the ISP offers wireless communications, telephone, data/broadband and internet services, the proxy should be residential
