Multilogin Proxy Setup
Isolate each Multilogin profile with its own SotaProxy IP.
Multilogin creates isolated browser profiles with unique fingerprints. Pair each profile with a dedicated SotaProxy endpoint to ensure complete IP separation between accounts.
Setup guide
Create or edit a profile
In Multilogin, create a new profile or edit an existing one. Navigate to the Proxy section.
Configure proxy settings
Set Type to HTTP. Enter proxy.sotaproxy.com as the host and 10000 as the port. Enter your SotaProxy username and password.
Assign unique session per profile
# Profile 1
Username: YOUR_USERNAME_s_1001_ttl_1h
# Profile 2
Username: YOUR_USERNAME_s_1002_ttl_1hUse unique session IDs per profile. This guarantees different IPs even when multiple profiles run simultaneously.
Automate it with the SotaProxy API
Everything above works without opening the dashboard. With an API key, Multilogin can pull fresh proxy credentials, buy new proxies, and renew expiring ones - straight from code.
# Every active proxy on your account (ip, ports, login, password as JSON)
curl -H "Authorization: Bearer $KEY" https://api.sotaproxy.com/api/v1/proxies
# Buy more when you scale (price-check first with POST /quote)
curl -X POST https://api.sotaproxy.com/api/v1/orders \
-H "Authorization: Bearer $KEY" -H "Content-Type: application/json" \
-H "Idempotency-Key: my-unique-order-id" \
-d '{"product":"ipv4","countryId":565,"periodId":"1m","quantity":5}'What goes into the profile proxy form
Multilogin asks for five fields and nothing else. Residential targeting rides inside the login, so you never need a separate endpoint per country:
Multilogin lets you save the proxy at the profile level or reuse a saved entry across profiles. Save it per profile: shared entries are how two accounts end up on one address by accident.
One session id per profile, forever
The number after _s_ is what ties a profile to an address. Give every profile its own and never reuse one, because two profiles on the same id share an address and that link is the cheapest signal a platform can compute:
Login strings for a fleet
profile_01 -> login_c_US_s_1_ttl_1h
profile_02 -> login_c_US_s_2_ttl_1h
profile_03 -> login_c_GB_s_3_ttl_1h
profile_04 -> login_c_DE_s_4_ttl_1h
# static address instead of residential:
# host = the IP from your dashboard, port 50100, no suffixes- One hour is the longest sticky lifetime we offer, and a residential device can drop earlier. For accounts that must never see an address change, buy an ISP address instead and put it in the same form.
- Match the profile timezone, locale and language to the proxy country. An account on a German address reporting a Warsaw timezone contradicts itself.
- Check the address inside the profile before the first login, not from your own browser. What matters is what the profile sees.
- Keep a note of which session id belongs to which profile. Rebuilding that mapping after a crash is painful and mistakes cost accounts.
What gets accounts linked
Two profiles on one address
Whether through a shared session id or a shared static address, this is the fastest way to lose a cluster: one flagged account takes the rest with it.
Changing country under a live account
An account that always logged in from Poland suddenly appearing on a German address reads as a takeover, and the platform asks for a phone number you may not have.
Rotation under a logged-in session
When a sticky hour expires mid-session the platform sees the session teleport. Long-lived accounts belong on ISP addresses.
Shared proxy entries
The convenience of picking a saved proxy from a list is exactly what puts two profiles on one address. Create a separate entry per profile even though it takes longer.
Notes & tips
- •Multilogin supports proxy import via API - automate proxy assignment when creating profiles programmatically.
- •Verify each profile's proxy with the built-in proxy checker before launching.
FAQ
Does Multilogin work with rotating proxies?
Yes. Use sticky sessions to keep the same IP for a profile's session. Rotate to a fresh IP by changing the session ID or letting the sticky window expire.
