How do you manage multiple social media accounts?
Short answer
Do three things. Switch between your own accounts with each network’s account switcher. Give other people a role, not your password: X has Delegate, YouTube has channel permissions, LinkedIn has Page admin roles, Instagram has shared access and Meta has partner access for Pages. Then publish from one place: Meta Business Suite for Facebook, Instagram and Threads, and a tool that uses each network’s API for the networks of other companies.
Switching between accounts you own
Each network has its own way, and some limits you only meet later. From their help pages, read on 10 October 2026:
| Network | What its help page says |
|---|---|
| Add accounts in the app and switch without logging out; up to ten can be logged in at one time (Instagram Help) | |
| X | Add an existing account from the side menu or your profile icon on mobile and desktop. X offers no way to merge accounts or move posts, followers or following from one to another (X Help) |
| Connect accounts that use different emails. You can switch only while you stay in the same browser session; clearing cookies or changing device ends it (Pinterest Help) | |
| TikTok | An email address or phone number can belong to only one TikTok account, so each extra account needs its own. A deleted account frees its email or number after 30 days (TikTok Help) |
Giving other people access without your password
When someone else posts for you, use the route the network built for it. Each of these is a role you can change or take away later:
| Network | The feature | What the person gets | Worth knowing |
|---|---|---|---|
| X | Delegate | Owner, admin or contributor roles; contributors can post, schedule and delete posts | Only the owner manages the password and login verification; the owner is responsible for what delegates post |
| YouTube | Channel permissions | Manager, Editor, Editor (Limited), Subtitle Editor, Viewer and Viewer (Limited) | An invitation by email expires after 30 days; the page says invited users can’t use YouTube APIs |
| Page admin roles | Super admin, content admin or analyst on a Page | Granted by an existing admin; content admins create and manage Page posts | |
| Facebook Pages (Meta) | Partner access | Full control of an asset such as a Page, or partial access to tasks such as creating content, managing ads and replying to messages | You need full control of the business portfolio, the partner needs a portfolio of its own and its ID, and two-factor authentication has to be on |
| Shared access | Post, like and comment as the account; inbox and story access are separate switches | Only eligible accounts, not teens; the number of invitees depends on a Meta One plan |
YouTube’s page says outright that permissions are safer than sharing a password, and X and Instagram describe theirs as working without one. A shared password also can’t be taken back from one person without changing it for everybody.
Publishing from one place
Switching accounts is not publishing. Two routes cover most setups:
- Meta’s apps. Meta Business Suite cross-posts between a Facebook Page, an Instagram profile and Threads while you create the post, when they sit in one business portfolio (Meta’s page). The details are in how to cross-post between Facebook and Instagram.
- Everything else. No network posts to another company’s, so a tool has to connect each account through that network’s API, with the account type each one requires. Post to multiple social media at once has the options, and what an agency needs from a tool is the longer checklist.
Managing several brands in Mellow Hub
Hub publishes to 9 networks from one login. A profile holds one brand’s accounts, with its own channels, schedule, queue and history, so two brands don’t share a calendar. Several accounts on one network are fine inside a profile, with one exception: each profile holds one Instagram account, and a second Instagram goes into a new profile. In Compose you pick the exact accounts for each post. The profiles guide has the steps.
Hub is for one account owner. Its pricing page says team seats, client logins and approval roles are not included. What it offers for delegation is an agent key or an OAuth grant, each with the channels, the mode, the daily limit and the expiry you chose, and each revocable.
- Create a Hub account.
- Connect your accounts in Channels. Each network’s own sign-in screen opens, so Hub never sees a password. Bluesky is the exception: Hub connects it with your handle and an app password, which you can revoke in Bluesky’s settings.
- Write the post in Compose, choose the channels and add the media. Where one network’s limit is shorter, give that network its own caption. The composer can shorten it for you.
- Hub checks every network’s rules before anything is sent: caption length, media count and type, a required title or board. It lists every problem at once, naming the network.
- Publish now or pick a time. Each network succeeds or fails on its own and returns its own link.
Hub is paid: plans start at $19 a month (Solo), after a 7-day trial with a card on file that costs nothing if you cancel before it ends, and a monthly plan's first month is 20% off. Publishing is unlimited on every plan, under a fair-use ceiling that stops automated floods (900 publications a month on Solo). One publication is one post on one account, so a post sent to five networks counts as five. There are no automatic overage charges.
Questions people also ask
Is it safe to give a social media manager my password?
Where a network offers roles, use them: YouTube’s help says channel permissions are safer than sharing a password, X’s Delegate works without sharing one, and Instagram’s shared access does too. A role can be changed or removed later without touching the password.
How many social media accounts can I be logged in to at once?
Instagram’s help says up to ten at one time. X’s and Pinterest’s help pages give no number. TikTok ties each account to its own email address or phone number.
Can I merge two social media accounts into one?
X says it has no way to merge accounts or migrate posts, followers or following. The other help pages we read for this answer don’t describe a merge, and we haven’t verified one.
Can someone manage my YouTube channel from a scheduling tool without owning it?
YouTube’s channel permissions page says invited users can’t use YouTube APIs, and a scheduling tool uses those APIs. The page doesn’t say how a tool should connect a channel you manage but don’t own, so ask the tool how it does it before you rely on it.
What should I write down for each account?
Which email address or phone number it is tied to, since TikTok allows one account per address or number; who holds which role; and what type of account it is, because publishing through an API needs an Instagram professional account, and Hub connects a Facebook Page rather than a personal profile.
