Which proxy protocol should I use in Multilogin, HTTP or SOCKS5?

SOCKS5. It carries all traffic types including UDP, performs better on media-heavy pages, and is less detectable than HTTP. NafeProxys supports both, but use SOCKS5 unless something specifically requires HTTP.

Why does my account still get flagged with a clean Multilogin fingerprint?

Almost always the IP or a location mismatch. Detection checks the ASN and whether your timezone, WebRTC and geolocation agree with the IP before it scores the fingerprint. A datacenter or recycled residential IP, or a timezone that does not match the proxy, fails those earlier checks regardless of fingerprint quality.

Should WebRTC be Disabled in Multilogin?

No. Set it to Altered (Masked) so it returns the proxy IP. Disabling WebRTC entirely is itself a detection signal, because most real users have it enabled. Altered is what a genuine device looks like.

Does Multilogin set the timezone automatically with a proxy?

Yes. When 'Check proxy' passes, Multilogin reads the IP's timezone, geolocation and WebRTC data and offers to sync the profile. Always accept it, and make sure your computer's system clock is set to update automatically or the masking can desync.

How many Multilogin profiles can one proxy handle?

One. Use a dedicated mobile IP per profile. Sharing a proxy across profiles is the fastest way to get accounts linked, because one ban on that IP affects every profile using it.

Are mobile proxies better than residential for Multilogin?

For account management and long sessions, yes. Mobile IPs come from real carrier ASNs behind CGNAT, so they carry high trust and can't be hard-blocked without affecting real subscribers. Residential pools are shared and degrade; datacenter IPs fail almost immediately.

Can I use sticky sessions for account management?

Yes. Hold one IP for the entire life of an account with no minimum duration. Rotate (per-request, scheduled, or API) only for background tasks inside throwaway profiles, never mid-session on a logged-in account.

Which carriers should I pick for Brazilian and Spanish profiles?

Brazil: Vivo or Claro. Spain: Movistar, Orange, or Yoigo. Match the carrier's country to the profile's language, payment method, and target audience.

My proxy connects but the profile won't launch, why?

Common causes: system timezone not on automatic, Service worker cache (Mimic) needing a reset, the Multilogin agent blocked on 127.0.0.1 by a firewall or extension, or the ISP blocking the proxy. Re-run Check proxy, fix the system clock, and test from a phone hotspot to isolate ISP blocks.

How do I scale to dozens of Multilogin profiles efficiently?

Use Multilogin's proxy template manager to apply a saved NafeProxys connection across many profiles, keep one IP per profile, hold sticky sessions for accounts, and automate creation with the Multilogin and NafeProxys APIs.

How do I get started with NafeProxys for Multilogin?

Sign up, pick Brazil or Spain and your carrier, start the 1-hour free trial with no card, add the SOCKS5 credentials to a test profile, run Check proxy, verify on browserleaks.com, and warm the profile before acting.
