Switching Antidetect Browsers Without Losing Your Accounts

A practical guide to migrating profiles, cookies, proxies, and 2FA to a new antidetect browser without losing accounts or access.

Teams switch antidetect browsers less often than you'd think, but when they do, it's rarely by choice. A vendor hikes prices overnight, drops support for the Chromium version you need, goes down for a week during peak season, or simply can't handle teamwork — no roles, no activity log, profile handoff means sending files through a chat app. Against that backdrop, switching looks like the obvious move. It's also where most accounts get lost — not because the migration is technically hard, but because teams rush it in a single day, with no plan and no fallback.

Here's how to move profiles without losses: what transfers easily, what needs care, and in what order to do it if you're dealing with three hundred profiles instead of three.

What actually needs to move

A profile in an antidetect browser isn't a single file — it's several layers stacked together, and each one behaves differently during a migration.

Fingerprint. OS, browser version, screen, GPU, canvas/WebGL/audio noise, timezone, language. Copying it literally is pointless and can even backfire: the platform already saw this fingerprint paired with the old browser engine, and a new engine means different rendering, different headers, different API behavior. Why small mismatches in a fingerprint are riskier than they look is covered in detail in the piece on fingerprint consistency. The right move is to generate a fresh, internally consistent fingerprint in the target browser, not stitch the old one back together piece by piece.

Cookies and session. This is the real value of a profile — what saves you from logging in and passing verification checks all over again. Cookies transfer as a file, but formats differ: some tools export Netscape format (plain text, tab-separated), others export JSON. If the target browser supports both import formats, there's no technical issue, but there's a catch with domains and expiry — more on that below.

Proxy. The profile's exit IP has to stay the same, otherwise you're layering a new network fingerprint on top of a new browser session — to the platform, that looks like a login from a different device and a different location at the same time, which raises the odds of an identity verification request.

2FA keys. If two-factor authentication is tied to an authenticator app rather than to the tool itself, this isn't an issue. But if the keys were stored inside the old tool, you need to export them and set them up again before you log out of the old instance — otherwise recovering access turns into a week-long support ticket with the platform.

History and bookmarks. Low priority, but for accounts where a believable activity history matters (warmed-up profiles, for instance), it's worth preserving at least part of it.

Team structure. Roles, per-member profile limits, who owns which pool of accounts. This is an organizational transfer, not a technical one, and it's often left until the last moment.

A step-by-step migration plan

1. Audit your profiles before moving

Before transferring everything, make a list: how many profiles are active, how many are abandoned, which are tied to live ad accounts or client accounts, and which can simply be closed. In practice, teams with 100+ profiles find that 15–25% is dead weight: test accounts, profiles from people who've left, duplicates. Migrating those just burns time and money on the new tool's plan. If the pool hasn't been inventoried in a while, it's worth cleaning house first using the approach in the piece on organizing profile pools at scale, then migrating.

2. A pilot group, not everything at once

Pick 5–10 low-risk profiles — not your key ad accounts, not accounts with money sitting in them — and migrate those first. This surfaces problems with cookie export formats, with a specific platform, with a proxy provider, before you've moved the entire fleet. A common mistake is migrating everything overnight because "the old plan expires Monday." It's better to run both tools in parallel for a few extra days than to spend the following week figuring out why 40 accounts simultaneously asked for identity verification.

3. Export and import cookies

Export cookies from the old browser in an available format — JSON or Netscape. When importing into the new one, check that:

• the domain and subdomains match (cookies set on .facebook.com versus www.facebook.com aren't always interchangeable for some platforms);
• the expiry hasn't already passed — if the export was done a while ago, some session cookies may have already died, and importing won't bring them back;
• the Secure and HttpOnly flags survived the format conversion — some homemade converters strip them, and the platform silently drops the session on the first request.

In GetAntik, cookies import and export in both JSON and Netscape, and you can schedule a cookie warm-up after the transfer so the session refreshes naturally instead of sitting in a half-alive state.

4. Move proxies one-to-one

The most important rule: one profile, one unchanged exit IP, before and after the move. If the proxy is rented from a separate provider, just plug the same credentials into the new browser's proxy manager and check the result — country, ASN, and type (residential/datacenter/mobile) should match what the platform saw before. If proxies were bundled into the old antidetect browser as part of the plan, you'll need to buy them separately — budget for that ahead of time, not on migration day. What proxy type fits which task is covered in the article on choosing proxies for multi-accounting.

5. 2FA and access recovery

Export secret keys (usually a TOTP seed string) from the old vault and set them up in the new one before closing the old account in the previous tool. If the keys can't be exported at all, that's a red flag about how that tool was storing sensitive data in the first place — without any way to get it back. More on how 2FA storage and profile encryption should work is in the piece on profile security. In GetAntik, 2FA keys live in the profile's vault, and profile data itself is encrypted on the device with the account password — the server can't read it.

6. Rebuild the team: roles and limits

This is the step most often left for the last minute, and done poorly as a result. Write down who currently has access to which profiles in the old tool, what limits and permissions they have, and recreate that in the new one — rather than giving everyone access to everything "until we sort it out." The difference between an admin role and a member role, per-member limits, and handing off a profile between teammates without sharing a password is covered in the article on team roles and profile handoff. In GetAntik, roles — owner, admin, member, finance — come with configurable permissions and per-member profile limits, plus an activity log so you can see who accessed which profile and when.

Table: what transfers easily, what needs attention

Common mistakes during migration

Moving the entire fleet in one evening. The more profiles you migrate at once, the higher the chance that a cookie format issue or a platform-specific quirk shows up across dozens of accounts at once instead of two test ones.

Switching proxies "while we're at it anyway." If both the browser engine and the exit IP change at the same time, it's harder for the platform to recognize the same user, and security checks trigger more often. Change one variable at a time if you have the choice.

Ignoring dead profiles. Migrating 300 profiles when only 220 are actually in use means overpaying for a plan and doing extra work for nothing. Auditing before the move saves both money and time.

Sending passwords and keys through chat apps "just this once." During a migration, a team is especially exposed: data temporarily exists in two places — exported files and chat history. Use in-tool profile handoff wherever possible instead of copying credentials by hand.

No rollback plan. If the old tool is still paid through the end of the month, don't shut it down right after migrating. Give yourself a week to confirm that all transferred profiles log in reliably, platforms aren't asking for re-verification, and proxies aren't getting blocked.

When migration is part of scaling up

Sometimes a tool switch coincides with team growth — five profiles per person becomes five hundred profiles across five people. In that case, plan for cross-device sync from the start: if people work from more than one laptop, a profile needs to open correctly on another device without losing cookies or settings. More on that in the piece on syncing profiles across devices.

Before migrating, it's worth checking the team features overview and the pricing page to figure out which plan covers your profile fleet after the move, rather than running out of room mid-migration. The app for macOS or Windows is available on the download page.

FAQ

How much time should I budget for migrating 100+ profiles? Realistically, one to two weeks with a pilot group — not a single day. Most of that time goes not into the technical transfer but into confirming that accounts log in reliably afterward without triggering re-verification.

Can a fingerprint be copied one-to-one between different antidetect browsers? Technically, partially — but it's not a good idea. Different engines render canvas and WebGL differently even with identical declared parameters, and the result can look more suspicious than an honestly generated new fingerprint.

What if the old tool doesn't let me export 2FA keys? Log into each account manually, disable the old two-factor setup, and set up a new one while saving the seed key. It's slow, but safer than losing access entirely if the old device gets lost.

Do I need to change proxies when switching antidetect browsers? No, not if proxies weren't bundled into the old tool's plan. Keeping the same exit IP is one of the main conditions for a smooth migration.

What about profiles shared by several people in rotation? Before migrating, note who last accessed the profile and what state it's in, so you don't transfer a session mid-task. After the move, set roles and limits up fresh rather than relying on memory of "how it used to be."
