Warm up new profiles
Let a profile browse ordinary sites like a person for a while, so its cookie jar and history are not empty the first time it matters.
On this page
A brand-new profile has no cookies and no history, and that on its own is a signal. The warm-up robot opens the profile as itself — real proxy, real fingerprint — and browses ordinary, high-traffic sites like a person: real scrolling, real clicks on links, unpredictable timing. It never signs in and never touches a form.
Part of Pro, Team and Custom.
🍪 Warm up one profile#
- Go to All profiles.
- On the profile's row, click ⋯, then Warm up cookies….
- Pick an Intensity, and edit Sites to browse (one per line) if you want to.
- Click Start warming.
The row's state column shows the progress: 🍪 warming up…, then 🍪 warming {i}/{total}, and — pausing between sites. Hover it to see which site it is on. To stop early, open ⋯ again and click Stop warm-up.
👥 Warm up several#
- On All profiles, tick the profiles you want.
- In the dock at the bottom, click the flame button (Warm up).
- Choose the intensity and the sites, then click Warm up {n}.
There is no queue
Every profile you pick opens its own browser straight away. Warming 30 profiles opens 30 browsers at once. Do them in batches your computer can carry — unlike Run on many… for Flows, there is no concurrency limit here.
Profiles that are already open are skipped without a message, so the count in the toast may be lower than the number you ticked.
🔥 The three intensities#
| Intensity | Sites per run | Pages per site | Roughly how long |
|---|---|---|---|
| Light — a few sites, a page or two each | 3–5 | 1–2 | a few minutes |
| Normal — a handful of sites, a few pages each | 5–8 | 2–3 | 5–15 minutes |
| Thorough — many sites, deep visits | 8–12 | 2–5 | 15–45 minutes |
The sites are a random subset of your list, and the time spent reading each page is random too, so two profiles warmed with the same settings do not produce the same history.
🌐 The site list#
The box comes pre-filled with neutral, cookie-heavy sites: Wikipedia, Bing, DuckDuckGo, Reddit, YouTube, Amazon, IMDb, Weather.com, BBC News, the New York Times, CNN, The Verge, ESPN, Etsy and Pinterest. Clearing the box puts the defaults back.
Change it if you want the history to lean a particular way — shopping sites before a shopping account, news before a news account — but keep it broad. A list of five sites all about one subject is its own kind of tell.
🤖 Warm up on a schedule#
Warm-up also exists as a Flow, which means it can be scheduled:
- Flows → Templates → add Warm up: browse like a person.
- Tag the profiles you want warmed — for example
new. - Open the Flow, click Schedule…, pick Every day at a time and Every profile with a tag.
See Run Flows on a schedule. Inside any Flow you build yourself, the same thing is available as the Browse like a person step, which takes minutes, a site list and pages per site.
🛟 Messages you may see#
- {profile} warmed up — {pages} pages, {cookies} cookies — done. The browser closes at the end, which is what writes the cookies to disk.
- hit a bot check — skipping this site — normal; it backs off rather than pushing through. Two bot checks in one run and it stops early.
- this profile is already warming up.
- open on another computer — warm it there, or take it over first.
- Firefox profiles cannot be warmed up: use a Chromium profile. See Chrome or Firefox.
ℹ️ Good to know#
- Warm-up always uses a visible window. A headless browser is itself a fingerprint, so there is no point hiding this one.
- It runs in memory: quitting LoginDeck ends any warm-up in progress.
- It logs into nothing and types into nothing, so it cannot get an account into trouble on its own.
- One pass is not a history. A new profile is better off warmed a little each day for a few days than hammered once — that is what the nightly schedule above is for.
- Warming a profile before you sign in to a new account is the point of it. See Good habits that keep accounts safe.
