Can I Use Claude on Multiple Devices at the Same Time?

Yes, you can use Claude on multiple devices at the same time: one Claude account can stay signed in on your laptop, your work computer and your phone at once, your conversations sync between them, and Anthropic doesn't publish a limit on how many devices you use.

The catch is usage. Every device, and Claude Code, draws from the same usage limit on your account, so working on two computers at once just reaches that limit faster. Below: how multi-device use works, whether you can run Claude Code on two machines, how to keep two Claude Code accounts on one computer, and where account sharing crosses the line. Everything here was checked against Anthropic's help center, the Claude Code docs and claude.com/pricing on November 14, 2026.

Key takeaways

• One account, many devices: sign in with the same email on the web, the desktop app and the mobile apps. Conversations, projects, memory and preferences sync.
• No published device cap, but one usage limit: chats, Claude Code and the desktop app all draw from the same 5-hour and weekly limits.
• Claude Code on two computers at once works with the same login, and it counts toward the same limits as your chats.
• Two Claude Code accounts on one computer: give each its own CLAUDE_CONFIG_DIR folder, or switch with /logout and /login.
• Sharing your login with another person isn't allowed under Anthropic's Consumer Terms. A Team plan gives each person their own seat.

Can I use one Claude account on two computers at the same time?#

Yes. To use your account on another device, Anthropic's login help article says to "enter the same email address you use to log in on your usual device." You can be signed in at the same time on:

• claude.ai in any web browser
• The Claude desktop app for Mac and Windows
• The Claude apps for iPhone and Android
• Claude Code in a terminal or code editor, on paid plans

According to Claude's download page, your conversations, projects, memory and preferences sync across all devices when you're signed in. A chat you start on your office PC is waiting on your phone when you leave. The one exception is a local session in Claude Cowork, which stays on the device that ran it.

Anthropic doesn't list a maximum number of devices or simultaneous sessions in its help center, pricing page or terms. That isn't a promise of "unlimited," though: the pricing page says Anthropic may limit usage "in other ways" at its discretion to manage capacity.

See and sign out of your other devices#

Claude keeps a list of every device and browser where you're logged in. To see it, click your initials in the lower left, go to Settings > Account and scroll to Active sessions (called Where you're logged in in the newer settings layout). Each entry shows the browser and operating system, an approximate location and when it was last used. Select the ⋮ menu next to a session and choose Terminate to log that device out (Anthropic's guide).

To sign out of every device at once, use the Log Out button in Settings > Account on claude.ai. According to Anthropic's help article, it signs you out of:

• web browsers, the mobile apps and the desktop apps;
• Claude Code, including long-lived tokens made with claude setup-token;
• Claude in Chrome and Claude in Slack.

It doesn't affect API keys, and the option isn't available in the iPhone or Android app. It's worth doing if you signed in on a hotel business center or library computer and forgot to log out.

How usage limits work across devices#

Usage limits belong to your account, not to each device. Claude's pricing page says your activity across Claude on web, desktop, mobile and Claude Code "all draws from the same pool." Most plans have a limit that resets on a rolling five-hour window, and paid plans add a weekly limit on top.

Prices don't include tax. The plan once called Max 20x is now Ultra, at the same price.

So a second device doesn't double your allowance. If you're on Pro and you run a long Claude Code task on your desktop while you chat with Claude on your phone, both draw down the same five-hour window. To see where you stand, open Settings > Usage on claude.ai, which shows your current session, your weekly limit and when each resets. When you reach a limit, you can wait for the reset, move to a bigger plan, or, on paid plans, turn on usage credits to keep going at standard API rates.

Can I run Claude Code on two computers at the same time?#

Yes. Install Claude Code on each machine, run claude and sign in with the same Claude account. Anthropic's Claude Code plan article says "these limits are shared across Claude and Claude Code," so both computers, and your chats, count toward the same usage. The docs don't list a cap on concurrent Claude Code sessions, whether they're on two computers or in two terminals on one.

Two things to check on each machine:

• Which account is active. Type /status at the Claude Code prompt to see the account and login method in use.
• Your usage. Type /usage to see your plan's usage bars. Its breakdown of what used the most is computed from that machine only; the docs note that "usage from other devices or claude.ai is not included."

One trap catches a lot of people: if the ANTHROPIC_API_KEY environment variable is set on a computer and you approve it, Claude Code uses that API key instead of your subscription, and you pay standard API rates for that usage. If one machine bills differently from the other, that's the first place to look.

Can I use multiple Claude Code accounts on the same computer?#

Yes. Say you're a freelance developer in Austin with a personal Pro account and a seat on a client's Team plan. You have three ways to use both on one laptop.

Option 1: Switch with /logout and /login#

Type /logout at the Claude Code prompt, run claude again and sign in with the other account in the browser window that opens. This is the simplest option when you only need one account at a time. Logging out also resets Claude Code's first-launch setup, so it walks you through setup again.

Option 2: Stay signed in to both with CLAUDE_CONFIG_DIR#

To stay signed in to multiple accounts at once, Anthropic's authentication docs say to give each account its own configuration folder with the CLAUDE_CONFIG_DIR environment variable. Each folder has its own settings, session history and login.

On a Mac or Linux, add this line to ~/.zshrc or ~/.bashrc (it's the example from Anthropic's docs):

alias claude-work='CLAUDE_CONFIG_DIR=~/.claude-work claude'

On Windows, add this function to your PowerShell profile (run notepad $PROFILE to open it):

function claude-work {
  $env:CLAUDE_CONFIG_DIR = "$HOME\.claude-work"
  try { claude @args } finally { Remove-Item Env:CLAUDE_CONFIG_DIR }
}

Open a new terminal and run claude-work. The first time, Claude Code walks you through login and setup for the new folder, so sign in with your work account there. From then on, claude opens your personal account and claude-work opens your work account, and you can keep both open side by side in separate terminal windows.

A few things to know:

• Your settings don't carry over. Each folder has its own settings and session history, so copy anything you rely on, such as settings.json, from your default ~/.claude folder. A project's own CLAUDE.md still loads in both, because it lives in the project.
• Credentials are stored per folder. On Windows and Linux, Claude Code keeps the .credentials.json file in each folder; on a Mac, it keeps a separate Keychain entry for each folder.
• One exception: separate folders don't keep two Claude Console sign-ins apart if you signed in to Console without an API key, because Claude Code stores that kind of sign-in outside the configuration folder.

Option 3: Use an API key for one account#

If your company pays for Claude Code through the Claude Console instead of a Team plan, you can set ANTHROPIC_API_KEY in the terminal where you do that work. After you approve the key once, Claude Code uses it instead of your subscription, and that usage is billed per token. To go back to your subscription, remove the variable (unset ANTHROPIC_API_KEY in Bash or Zsh, Remove-Item Env:ANTHROPIC_API_KEY in PowerShell) and confirm with /status.

Can I have more than one Claude account?#

Yes. Anthropic's help center explains how to switch between a personal account and a work account, and how you do it depends on the email address:

• Same email, personal plus Team or Enterprise: click your initials in the lower left of the Claude app and pick the account. A check mark shows the active one (help article).
• Different emails: there's no switcher in the apps. Log out, then log in with the other email address. In Claude Code, use one of the options above.

Every new account needs a phone number that can receive text messages, and Anthropic's verification article says a maximum of three Claude accounts can be verified with the same number. VoIP numbers, Google Voice and landlines aren't accepted. One more limit: Anthropic's Usage Policy bans using extra accounts to get around its safeguards or a suspension.

Can you share a Claude account with someone else?#

No. Section 2 of Anthropic's Consumer Terms says "You may not share your Account login information" and you may not make your account available to anyone else. The login help article adds that subscription plans "can only be used by subscribers." Anthropic can suspend or close an account that breaks its terms, and sharing also hands the other person your chat history, memory and connected apps.

If two or more people need Claude, a Team plan is the supported route: it covers 2 to 150 people, and each seat is assigned to one named person. Standard seats cost $25 per month billed monthly, or $20 per month billed annually, as of November 14, 2026. For a couple or a small family, separate Free or Pro accounts do the same job.
