What Is accountsd?

accountsd manages the internet accounts in System Settings › Internet Accounts (iCloud, Google, Microsoft, Exchange and others) and gives apps like Mail, Calendar and Contacts access to them.

No. accountsd keeps your accounts signed in.

It refreshes sign-ins and tokens over the network.

accountsd is “partly” network-related: most of its work is local bookkeeping, but it contacts account providers to refresh credentials. If it's stuck at high CPU, open System Settings › Internet Accounts and look for accounts asking for a password, and remove accounts you no longer use.

Should you worry?

No. accountsd keeps your accounts signed in. Occasional high CPU usually comes from an account with a problem: wrong password, expired token or a large sync.
