# Mosaic for social media managers > Keep each brand's social logins, two-factor codes and notes in their own browser profile, on their own exit, and check posts as the brand's market sees them. Source: https://mosaicbrowser.com/use-cases/social-media-teams ## Mosaic for social media managers running brand accounts Social media managers use Mosaic to keep each brand or client account in its own browser profile, with its own logins, two-factor codes, notes and exit address. Platforms' own tools for page roles and multiple accounts come first; Mosaic keeps the accounts you are allowed to run apart. ![Each brand in a window of its own, beside a screenshot: six Mosaic profile windows arranged in a grid, each with its own name in the title bar](https://mosaicbrowser.com/covers/social-media-teams.webp) A social media manager with six brands has six sets of logins, six two-factor devices to ask about, six content calendars and one browser that keeps logging into the wrong account. The platforms help with some of that. Mosaic helps with the part they leave to the browser. ## What the platforms allow, and their own tools Each platform decides how many accounts a person may run and how others may help manage them, and those rules come first. - **LinkedIn**: the User Agreement says you "will only have one LinkedIn account, which must be in your real name", and forbids using someone else's account, including by sharing log-in credentials or copying cookies (LinkedIn, read 2 November 2026). Company pages are managed through page admin roles, not through a client's personal login. - **Meta**: a business can share its Pages and ad accounts with a partner, such as an agency, through its business portfolio (Meta Business Help Center, read 2 November 2026). - **Instagram**: the app itself lets you add several accounts and switch between them (Instagram Help Center, read 2 November 2026). Mosaic keeps accounts you are entitled to run apart; it does not change what a platform allows. It is not for fake engagement, sockpuppets or getting back onto a platform that has closed an account, and we will not help with those.

[How it works: Local first](https://mosaicbrowser.com/features/local-first) ## Where Mosaic fits Brands often have logins of their own that a manager signs into directly: a brand's own account on a platform without an agency mode, a regional account the brand wants worked from its market, a client's tools that only have a username and a password. Those are the accounts that benefit from a browser of their own. 1. **One profile per brand account.** Cookies, history and saved logins belong to that brand only, so a reply never goes out from the wrong account. 2. **Each with its own exit.** A [provider](https://mosaicbrowser.com/features/proxy-providers) mints a separate proxy session for every profile, so brands do not share an address. The profile's timezone and language follow the measured exit. 3. **Its codes and notes in the browser.** Each profile has a credential vault with two-factor codes, and the companion shows that brand's logins, codes and notes, in Markdown, inside the brand's own window. ![Six Mosaic profile windows arranged in a grid, each with its own name in the title bar](https://mosaicbrowser.com/shots/windows-arranged.png) *Six brand profiles arranged side by side, each window labeled with its profile name.* ## Working across brands Every Mosaic window carries its profile's name next to the address bar, so six open brands are six labeled windows instead of six identical Chromes. Bulk actions start a set of profiles together and arrange their windows on screen; you can open the same page in all of them, such as each brand's notifications page, at the start of the day. A new brand account opened in a new profile can be warmed up first. The warm-up robot has a social and media plan that browses everyday sites in the profile's own browser and through its own proxy, so the profile has a history before it signs in anywhere. ## Checking what followers see A profile with an exit in the brand's market sees the platform's local version: the regional feed, local trends, the language a follower sees. That is useful for checking a campaign landed the way it was meant to. The proxy is checked before each launch, and a profile never opens behind one that has not answered. ## What it does not do Mosaic does not schedule posts, has no shared inbox and has no team seats. Profiles live on the computer that made them, which keeps every brand's sessions off third-party servers, as [local first](https://mosaicbrowser.com/features/local-first) explains, and means two managers cannot open the same profile from two laptops. For team work, use each platform's roles; use Mosaic for the sessions on your own desk.

LinkedIn's User Agreement says each person has one account in their real name and forbids using someone else's account, including by sharing logins or copying cookies. Use Page admin roles for company pages instead. ### Does Mosaic post on a schedule? No. Mosaic is a browser, not a scheduling tool. Keep using your scheduler; Mosaic holds the logged-in sessions and codes for the accounts you work on by hand. ### Can my whole team use the same profiles? Not at the same time. Mosaic has no team seats and profiles live on one computer. For several people on one brand, use the platform's own roles, such as Meta's business portfolio. ### How do I see a post the way followers in another country do? Open the brand's profile with an exit in that country. Mosaic sets the profile's timezone and language from the measured exit, so the platform serves the local version. ## Related [Mosaic for agencies and media buyers managing ad accounts](https://mosaicbrowser.com/use-cases/ad-account-management): Keep each client's ad platform logins, two-factor codes and sessions in their own browser profile, and see their ads from the client's own market.
