How to Set Up a Proxy in Undetectable Browser

Undetectable is an antidetect browser where every profile gets its own fingerprint and its own proxy. The proxy is set on the profile itself, so it takes about two minutes and nothing else on your computer changes.

This guide follows the video step by step, using one of our dedicated SentraCell proxies over SOCKS5. HTTP works the same way; you just pick a different type in step 4.

What You'll Need

• •Undetectable, installed from undetectable.io and signed in. The free plan is enough to follow along.
• •Your SOCKS5 login: host, port, username and password. SentraCell customers get it in @sentracell_proxies_bot on Telegram.
• •Your rotation link, optional. It lets you change the IP from inside Undetectable.

Step-by-Step Setup

• 1
  Copy your SOCKS5 login. In the SentraCell bot, tap Manage ID credentials, pick your proxy and copy the SOCKS5 string. It comes as host:port:username:password, which is the format Undetectable expects.
• 2
  Click New profile. It's the button at the top of the Profiles page.
• 3
  Open the proxy section. Click the proxy icon in the new profile, then the dropdown that says No proxy, then New proxy.
• 4
  Pick the type. Choose SOCKS5 (or HTTP if that's the login you copied).
• 5
  Paste the login. Undetectable takes the whole host:port:username:password line. If it lands in one field instead of splitting, fill in host, port, login and password by hand.
• 6
  Click Check proxy. After a second it shows the proxy's IP and location. In the video that's Austin, Texas, where that phone lives. A green status means it works.
• 7
  Name the profile and click Create. Any name works; in the video it's "test one".
• 8
  Start the profile with the play icon, open whatismyip.com, and check the result. It should show a mobile IP from your proxy's carrier, Verizon in Texas in the video, not your home connection.

How to Rotate Your IP

Open the SentraCell bot and tap Rotate IP, or use the IP change option in Undetectable's Proxy Manager if you filled in the link. The phone reconnects to the carrier and comes back with a new IP in 5 to 10 seconds. The profile stays open and uses the new IP on the next page load.

If It Doesn't Work

Check proxy fails or stays red. Copy the string from the bot again and paste it fresh. A space at the start or end is the usual cause. Also make sure the type matches the login you copied: SOCKS5 for the SOCKS5 string, HTTP for the HTTP one.

The profile shows your real IP. The proxy wasn't attached. Open the profile settings and make sure the proxy dropdown shows your proxy, not "No proxy".

Location looks wrong. Check proxy shows the carrier's registered location, which can be a nearby city. The IP will still be a US mobile IP from the right carrier.

Undetectable Proxy FAQ

Can I reuse one proxy on several profiles?

You can pick it from the Select proxy dropdown on any profile, but then those profiles share one IP. For accounts that need to look unrelated, use one proxy per profile.

SOCKS5 or HTTP?

Both work in Undetectable. SOCKS5 is the better default because it carries every kind of traffic. Use HTTP only if a tool you're running needs it.

Does the proxy stay saved?

Yes. It's stored with the profile, and if you added it through the Proxy Manager it's in your proxy list for any future profile.
