Add a Second User Account
If you share your OnePlus phone with a family member or colleague, mixing personal apps, messages and login data quickly becomes a hassle. A separate user profile keeps each person's home screen, apps and app data apart, while things like Wi-Fi settings still stay shared across the device.
Switch Between User Accounts
If several people share the same OnePlus phone, jumping into full system settings just to swap accounts feels slow. Each user profile keeps its own apps, wallpaper and data separate, so picking the wrong one mid-task can mean losing your open apps or notifications. The switch actually lives in the quick settings, not buried in a settings menu.
Remove an Account on OnePlus
Old logins pile up in the account overview on your OnePlus phone and make it harder to spot the ones you actually use. Removing an account deletes its login credentials and any data that was synced through it, while the app it belongs to stays installed. This matters most for accounts like WhatsApp or Facebook, where contacts, messages, or cloud-synced content tied to that login disappear from the device once it's removed.
Enable or Disable Auto-Sync for Personal Data
Contacts, calendar entries and app data can update automatically the moment you change them online or on another device. If Auto-sync personal data is switched off, those changes stop reaching your OnePlus phone until you sync manually or turn the option back on.
Add a Second Account
After the first setup, your OnePlus phone only keeps the Google Account you signed in with during activation. If you use a second Gmail address, a work Exchange account, or an Outlook inbox, none of that syncs until you register it separately. Apps like Facebook or WhatsApp handle their own login and never show up in this list.
Delete a User Account
When a family member or guest no longer needs access to your OnePlus phone, their user account still sits in the multi-user list with all its apps and data intact. Leaving unused accounts active wastes storage and can expose personal content to anyone who switches profiles. Removing the account permanently wipes everything tied to it, so only the owner or an administrator should trigger the deletion.
