Every term LoginDeck's screens use, in plain words, with a link to the page that covers it properly.

A#

  • Advanced tab — the part of the profile editor holding the fine fingerprint controls, such as canvas and WebGL behaviour. Safe to ignore until a site gives you a reason to open it. See Fingerprint settings, explained.
  • AI action — one unit of LoginDeck's included AI: building a Flow step, repairing a broken one, or reading a page. Your plan includes a monthly allowance. See LoginDeck AI actions.
  • Antidetect browser — an app that runs many separate browsers, each looking like its own computer, so several accounts on one site don't appear to share a machine. See What LoginDeck is and how it works.

B#

  • Browser engine — the browser LoginDeck runs your profiles on: its own Chromium, or its own Firefox. Not your everyday Chrome. See Chrome or Firefox, and which browser version.
  • Bulk actions — the dock that appears at the bottom of the profile list when you tick more than one row, holding the actions that make sense for a group. See Change many profiles at once.

C#

  • Client hints — a modern way for a browser to report its platform, brand and version to a site, alongside the user agent. LoginDeck keeps them agreeing with the rest of the profile's machine. See What a browser fingerprint is.
  • Computer limit — how many computers your plan allows on one account, counted over the last 30 days. Team members' computers count against the owner's limit. See Use LoginDeck on another computer.
  • Cookie sync — carrying each profile's cookies and site data between your computers, so a profile opens already signed in. Paid plans only. See Cookie and session sync.
  • Cookies — the small files a site uses to remember that you're signed in. Each profile has its own set, and they never mix. See Import and export cookies.

E#

F#

  • Fingerprint — the collection of traits a site reads to tell one computer from another: operating system, graphics card, screen, fonts, language, timezone and more. LoginDeck gives each profile a consistent one. See What a browser fingerprint is.
  • Fingerprint check — LoginDeck's own report on a profile: it opens the profile in a scratch copy, reads it the way a detector would, and says whether every trait agrees. See Check a profile's fingerprint.
  • Flow — an automation you draw rather than code: steps wired from start to end, run on one profile or many. See What Flows are and what they can do.
  • Folder — the coarse grouping for profiles, one folder per profile. Team access is granted per folder. See Organise profiles into folders.
  • Free plan — 10 profiles on 2 computers, no card, no expiry, one free account per person. See The free plan.

H#

  • Headless — a browser running with no visible window, usually driven by a script. It's allowed through the local API, but a headless browser is easier for a site to spot. See Get started with the local API.

L#

  • Lease — the claim a computer takes on a profile while its browser is open, which is how LoginDeck stops the same profile running in two places. It lapses on its own within about two minutes if a computer crashes. See When someone else has a profile open.
  • Linked accounts — the logins you save with a profile (platform, email, password, its own 2FA key) so Flows can fill them in. See Saved logins and 2FA codes.
  • Local API — the small web service LoginDeck can run on your own machine, so your scripts and AI agents can open and drive profiles. Off by default, loopback only, and it needs a token. See Get started with the local API.
  • Locked profile — a profile your plan no longer covers. Nothing is deleted: it keeps its fingerprint, proxy and logins, but it can't be opened, exported or copied until you move up a plan. See "Free is full", locked profiles and other plan messages.

M#

  • MCP — Model Context Protocol, the standard LoginDeck uses to let AI agents such as Claude or Cursor drive your profiles. See Let AI agents drive LoginDeck.
  • Member — someone you invite into your workspace. They keep their own LoginDeck account and get access to the folders you choose, at the level you choose. See What members can see and do.
  • Mobile profile — a profile whose fingerprint is an Android phone rather than a desktop. See Android (mobile) profiles.

N#

  • New fingerprint — the button in the profile editor that regenerates the profile's whole machine from a new seed, keeping every trait consistent. See Edit a profile.
  • Notes — free text on a profile, editable straight from the list and searchable. See Tags and notes.

O#

  • Owner — the account that holds a workspace: the only one who can buy a plan, invite members or close the account. See How teams work.

P#

  • Profile — a browser of its own, with its own cookies, storage, extensions, fingerprint and proxy. The thing everything else in LoginDeck is about. See Create a browser profile.
  • Profile defaults — what a freshly created profile starts with: engine, operating system, language and so on. Saved on this computer only. See Default settings for new profiles.
  • Proxy — a server your profile browses through, so the site sees the proxy's address instead of yours. See Which proxy should I use?
  • Proxy device — your own Android phone used as a mobile proxy, with its carrier IP as the exit. See Use an Android phone as a mobile proxy.

R#

  • Recently deleted — the bin at the foot of the sidebar. Deleted profiles wait there for 30 days, with their cookies, before they're erased. See Delete and restore profiles.
  • Repairs — the record of the fixes LoginDeck's AI made to a Flow when a step broke, with before-and-after and a Keep or Put back choice. See When a Flow gets stuck.
  • Rotating proxy — a proxy whose IP changes, either on a timer or when you ask it to. See Change a proxy's IP.

S#

  • Saved proxy — a proxy stored once in the Proxies library and pointed at by profiles, so a changed password is one edit. See Add a proxy.
  • Schedule — a Flow set to run at a time you choose. Schedules run only while LoginDeck is open. See Run Flows on a schedule.
  • Seed — the single random value a profile's whole machine is generated from, which is what makes its traits agree with each other. See What a browser fingerprint is.
  • Session — a profile's logged-in state: its cookies and site data, captured when its browser closes. See Cookie and session sync.
  • Sync Actions — working in one profile while your clicks and typing repeat live in the others you picked. The page is titled Synchronized Actions. See Drive many profiles at once.

T#

  • Tag — a label you can put on any number of profiles, shown as tabs above the list. Up to 8 per profile. See Tags and notes.
  • Template — a ready-made Flow you copy into your own list and edit. See Start from a template.
  • TOTP — the rolling six-digit code an authenticator app produces. Paste a site's 2FA key into a profile and LoginDeck shows the code on every computer that profile syncs to. See Saved logins and 2FA codes.

U#

  • User agent — the line a browser sends naming its version and platform. LoginDeck builds each profile's from that profile's operating system and browser version, so it matches everything else. See What a browser fingerprint is.

W#

  • Warm-up — opening a profile as itself and browsing ordinary sites like a person, so a new profile doesn't look brand new. It never logs in or fills forms. See Warm up new profiles.
  • WebRTC — a browser feature for live audio and video that can reveal your real IP if it isn't handled. LoginDeck makes it follow the proxy. See WebRTC and IP leaks.
  • Workspace — one account's set of profiles, proxies, folders and Flows. Your own is always there, and joining a team adds theirs; switching between them switches the whole app. See Join a team and switch workspaces.
