TL;DR
Grab your proxy credentials from your Proxyon dashboard, open a profile in Multilogin, select Custom under the Proxy section, choose HTTP or SOCKS5, paste in your IP, port, username, and password, then run a proxy check before launching. Residential works best for social accounts; datacenter works best for high-volume automation.
Why the Proxy Matters

Multilogin automatically spoofs your fingerprint, but your IP address stays yours unless you use a proxy. Skip that step, and every profile still connects from the same source, no matter how different the fingerprints look. A Proxyon proxy closes that gap.

Getting Your Proxyon Credentials

Sign up at Proxyon. No identity verification required. Deposit $5 minimum, pick a proxy type, and generate your credentials: IP, port, username, and password. Keep the dashboard open while you set up the profile.
Adding Proxyon to a Multilogin Profile
- Open or create a browser profile in Multilogin.
- Scroll to the Proxy section and select Custom.
- Choose the protocol: HTTP or SOCKS5.
- Enter the IP or hostname and port from your Proxyon dashboard.
- Enter your username and password.
- Click Check Proxy. A pass confirms the connection.
- Save and launch.
Full reference on custom proxy fields is in Multilogin's own documentation.
Which Proxyon Proxy Type to Use

Residential proxies route through real household IPs, from $1.75/GB, best for social accounts and marketplace profiles that platforms watch closely.
Datacenter proxies are faster and cheaper, from $1.50/IP, best for bulk automation where speed matters more than blending in.
The core rule stays the same across every antidetect setup: one profile, one IP. Sharing IPs across profiles undoes the isolation Multilogin is built for, a point covered in detail in this antidetect browser comparison.

FAQ Section

Does Multilogin support Proxyon proxies?
Yes, through the Custom proxy option, which accepts any HTTP or SOCKS5 proxy.
Residential or datacenter for social media management?
Residential. Platforms flag datacenter IPs more aggressively on account-based work.
Can I reuse one Proxyon proxy across multiple profiles?
Not recommended. It breaks the IP separation that makes Multilogin effective.
What if the proxy check fails?
Confirm the protocol matches the port, and check your credentials and Proxyon balance.
Is a subscription required?
No. Proxyon runs on a pay-as-you-go, deposit-and-use basis.
Final Thoughts
Multilogin handles the fingerprint, Proxyon handles the IP. Residential is the right call for account management, datacenter for speed and volume. Deposit what you need, generate your credentials, and you can have a profile running in a few minutes, no subscription required.
