Proxies & IP masking FAQ
The importance of proxies
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
Our tip: always use high-quality proxies from reputable providers to avoid detection and keep your accounts secure. See how to choose a proxy type our use our built-in feature: Multilogin proxy!
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.
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
Best practice? If you need unique IPs for multiple profiles running simultaneously, consider using proxies instead of a VPN.
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
