MostLogin proxy setup

MostLogin proxy fields

1. Click Create profile, fill in the General tab, then open the Proxy tab and leave Type on Basic. A proxy saved earlier under Proxies is under Select proxy instead.
2. Set Proxy protocol to HTTP and fill in the fields below. Host:Port is one row with two boxes: the host on the left, the port on the right.
3. Click Check proxy server IP. It shows the exit's IP, city, time zone and postal code before you click Confirm.

Swap PROXY_USER / PROXY_PASS for the credentials on your dashboard. New here? Create an account to generate a key.

# Host gw.proxmint.com, port 823 (HTTP) or 824 (socks5), the same password in every profile.
# A distinct sessid gives each profile its own IP for up to 120 minutes.
PROXY_USER__cr.us;sessid.mst01;sessttl.120
PROXY_USER__cr.us;sessid.mst02;sessttl.120
PROXY_USER__cr.gb;sessid.mst03;sessttl.120
# No sessid: a new IP on every connection, for browsing rather than logins.
PROXY_USER__cr.us

Tips & gotchas

• Proxy protocol starts on socks5. Port 823 speaks HTTP and 824 speaks SOCKS5, so a profile left on socks5 with port 823 never connects: switch the protocol to HTTP, or keep socks5 and change the port to 824.
• Leave UDP Protocol unticked. Our SOCKS5 port carries TCP only and refuses UDP, and on HTTP the box doesn't apply.
• Leave Proxy rotate URL empty. It's for providers that change the IP when you call a link; here sessttl decides how long a profile keeps its IP, and a new sessid gets a new one.
• Proxy bypass (Settings › Proxy bypass) sends the domains you list over your own connection. It saves bandwidth on CDNs such as fbcdn.net, but a bypassed site sees your real IP, so never bypass a site you log in to. MostLogin adds a * to each entry, so the rule covers its subdomains too.
• Check proxy server IP shows the exit's city and time zone. A new session can land in a different city of the same country, so add ;city.newyork if a profile must keep one time zone. City targeting meters at 2× on every pool except premium residential.

What is MostLogin?

MostLogin is an antidetect browser for Windows and macOS. Each profile is an isolated Chromium environment with its own fingerprint, cookies and proxy, and profiles and proxies can be shared with a team. The free Starter plan covers 5 profiles, and paid plans are priced by profile count, from Plus (20 to 500 profiles) through Pro (600 to 10,000) to Enterprise. MostLogin also rents cloud phones: real Android devices hosted in the cloud.

MostLogin key features

• Fingerprints. Each profile has its own fingerprint, set on the Fingerprint tab, and an Overview panel shows the OS, browser version and user agent before you confirm.
• Proxies. Typed in per profile, saved once under Proxies and picked with Select proxy, fetched through API extraction, or batch-imported from a spreadsheet template.
• Team collaboration. Profiles and proxies shared with role-based access, and team activity tracked in one place. A saved proxy's Access is Me, Team view or Team edit.
• Extensions. Upload your own extensions or add Chrome ones, and enable them across every profile at once.
• Batch operations. Create profiles in bulk and update the proxies of many profiles together.
• Synchronizer. Mirror typing, tabs and window layout from one profile to the others.
• API and MCP. A local API drives profiles from your own scripts, and an MCP server connects AI tools such as Claude and Cursor to it.
• Cloud phones. Real Android devices in the cloud, billed per device at $25 a month or on demand at $0.10 per 15 minutes (up to $1.60 a day), plus a few cents a day for the environment.
