Rheos publishes to seven networks: Instagram, LinkedIn (personal profile and company pages), Facebook, X, Pinterest, Bluesky and Mastodon. Connect each account once, and Rheos keeps the connection alive where the network allows it.

​
Connections belong to a brand

Settings → Social Accounts lists your personal account first, then one section per business brand. Each section holds its own connections, and the networks on offer differ: Instagram, Facebook, Pinterest and LinkedIn company pages only appear under a business brand — you won’t find them under Personal. X, Bluesky and Mastodon appear in both, and are connected separately for each brand. Each section header shows how many accounts are connected, and turns amber with a count of how many need attention when one of them needs reconnecting.
Threads, TikTok and YouTube Shorts are coming soon. They already show up in the composer’s platform list, but there is no card for them in Settings → Social Accounts, so there’s no way to connect an account yet and nothing can publish to them. Ignore them for now.

​
How to connect an account

1

Open Settings → Social Accounts

From the sidebar, open Settings, then Social Accounts.
2

Pick the right brand

Pick your personal account, or the business brand this account belongs to.
3

Select Connect

Rheos takes you to that network’s sign-in page and brings you back when you’re done.
4

Confirm it's live

The card shows a green Connected badge with the account name. You can now select that network on a post.
Bluesky, Mastodon and X don’t quite follow that pattern — see below.

​
Platform notes

Rheos connects to Instagram directly, not through a Facebook Page. You need an Instagram Business or Creator account — personal accounts can’t publish through the API. If you’re switching from personal, do that in the Instagram app first, then connect.
Two separate cards. Personal Profile lives under your personal account; Company Pages lives under a business brand.Connecting company pages authorises every page you administer, but only one page publishes for that brand. If you admin more than one, Rheos asks which — until you pick, company-page posts for that brand can’t go out. Select Set active on the page you want. You can change it any time from the same list.If no pages appear, check you’re a Super Admin or Content Admin of the page on LinkedIn, then reconnect.
You connect a Facebook Page, not your personal profile. Make sure you’re a Page admin first.Rheos authorises every Page you grant and picks one as the publishing Page. If you manage several, the card names the Page posts go to — select Change to switch.
X reuses whatever X session your browser already has, so it can quietly connect the wrong account. Rheos shows a short dialog before sending you over: Open X logout, sign out, come back, then Continue to X and sign into the account you actually want.
Bluesky doesn’t use OAuth. Create an app password at bsky.app/settings/app-passwords, then type your handle (e.g. you.bsky.social) and that app password into the card and select Connect. Use an app password, not your account password.
Mastodon is federated, so Rheos needs to know which server you’re on. Type your instance (e.g. mastodon.social) into the card first, then select Connect to sign in there.
Standard sign-in and approve. Afterwards, pick the board Rheos should pin to — Pick board on the Pinterest card. Until a default board is set, Pinterest posts fail.

​
When a connection expires

Most networks issue credentials that expire. Rheos renews what it can, and asks you to reconnect only where the network makes that unavoidable.
Bluesky has no countdown, but it isn’t immune to needing you. Rheos refreshes the Bluesky session on every publish, and if Bluesky rejects that refresh the publish fails with a “Bluesky session refresh failed” error asking you to reconnect. That usually means the app password was revoked or changed — create a fresh one and reconnect the card.

​
When a connection needs attention

Two warnings exist, and they don’t start at the same moment:
  • The brand section header goes amber with a count — “1 needs attention” — from 14 days before a connection Rheos can’t renew for you runs out. That means LinkedIn without a refresh token, and Facebook.
  • The LinkedIn and Instagram cards inside count down separately, from 7 days out: “Token expires in N days”. Only the LinkedIn cards carry a Reconnect link — Instagram’s countdown is plain text.
So from 14 days out to about 8, the header flags something the cards haven’t spelled out yet. Nothing is broken and nothing has stopped working. Treat the amber header as the signal: reconnect from the card and it clears. The Facebook card carries no countdown at all — use the refresh icon on it.
The card countdowns run off the credential’s own expiry date, not off whether Rheos can renew it. Instagram’s says so outright — “It will be refreshed automatically” — and the section header stays green for it. A LinkedIn connection with a refresh token behaves the same way. Reconnecting anyway does no harm.
Reconnecting takes you back through the same sign-in as the first time; nothing else about the account changes.
If a scheduled post fails because a connection expired, the post isn’t lost. Reconnect, open the post, and use Retry failed. See publishing troubleshooting.
