Trying to sign in to Claude or the Claude Console and seeing an error such as:

This link has already been used

or:

This link has expired

can be frustrating, especially when you're simply trying to log in to your account.

Claude uses email-based magic links as one of its login methods. Instead of entering a traditional password, you enter your email address and Claude sends you a secure login link. According to Anthropic's current help documentation, this method is available both for Claude and Claude Console. (Anthropic Help Center)

The good news is that these errors usually don't mean your Claude account is gone. In many cases, the problem is related to how the login link was requested, opened, or used.

Here's what the messages mean and what you can try.

What is a Claude Magic Link?

A magic link is a one-time authentication link sent to your email address.

When you choose Continue with email on Claude, you enter your email address and receive an email with a subject such as “Secure link to log in to Claude.ai.” Claude Console uses a similar email called “Secure link to log in to Claude Console.” (Anthropic Help Center)

The process is intended to be simple:

Open Claude or Claude Console.
Enter your email address.
Request a login link.
Open the email.
Click the login link.
You're authenticated.

The problem occurs when Claude no longer accepts the link.

What does “This link has already been used” mean?

If Claude shows:

“This link has already been used”

it generally means the authentication link has already been consumed.

Magic links are designed to be used for authentication rather than as permanent URLs. If the link has already completed the login process—or the authentication attempt has otherwise consumed it—you may not be able to use that same link again.

The simplest solution is to request a completely new login link rather than repeatedly clicking the old one.

Try this

Close the Claude login page.
Return to Claude or Claude Console.
Enter your email address again.
Request a new login email.
Open the newest email.
Use that link once.

Avoid repeatedly clicking older Claude emails. If you have received several login emails, make sure you're using the most recent one.

What does “This link has expired” mean?

If Claude says:

“This link has expired”

the authentication link is no longer valid.

This can happen if the link is too old or if the authentication flow has already moved on to another login attempt.

Again, the best solution is usually to start a new authentication attempt.

Don't keep trying an old email. Instead, request a new magic link from the Claude login page.

One important detail: use the same device

One of the most important things to understand about Claude's login process is that the experience differs depending on whether you open the email on the same device or another device.

Anthropic says that if you request the login email and click the link on the same device, you should be redirected directly into your account.

If you request the link on one device but open the email on another, Claude can instead provide a verification code that you enter on the original device. (Anthropic Help Center)

For example:

Computer → request login → computer → click link

is the simplest workflow.

But:

Computer → request login → phone → open email

can result in a verification-code flow.

This distinction is particularly important if you're trying to log into the Claude desktop application.

Some users have reported difficulties getting authenticated in the Claude desktop application, particularly when the email verification process doesn't behave as expected.

A Reddit discussion in the Anthropic community also describes users experiencing problems with email verification and Claude Desktop login. Community reports aren't official documentation, but they can be useful for identifying patterns users are seeing in the real world.

That doesn't necessarily mean there is a permanent Claude Desktop problem. Authentication issues can also be caused by an expired link, an interrupted login session, browser state, email security systems, or a temporary service-side problem.

How to fix the Claude Magic Link error

Here are the steps I'd try, in order.

This should be your first step.

Go back to Claude and enter your email address again.

Don't keep using the link from an older email.

If multiple emails arrive, use the newest one.

2. Open the link on the same device

If you're trying to log into Claude Desktop on your computer, start the login process on that computer and, if possible, open the email on the same computer.

Anthropic specifically documents different behavior when the email link is opened on another device. (Anthropic Help Center)

This is one of the easiest things to try.

3. Don't click the same link multiple times

A magic link isn't something you should repeatedly refresh or reuse.

If you clicked the link once and got an error, don't keep clicking that same email.

Instead:

Start over → request a new link → use the new link once.

4. Check your email carefully

Anthropic recommends checking your spam and junk folders if the login email doesn't arrive.

You should also check whether your organization's email system has quarantined the message.

Anthropic recommends allowing emails from:

@mail.anthropic.com

if your email provider or organization is filtering them. (Anthropic Help Center)

This can be particularly relevant for corporate, university, or government email accounts.

5. Wait a few minutes and try again

If you request multiple login links in quick succession, it can become difficult to know which email corresponds to the current authentication attempt.

Rather than requesting link after link, give the system a moment and then start one fresh login attempt.

Anthropic's own troubleshooting guidance recommends trying again after a few minutes if the login email hasn't arrived. (Anthropic Help Center)

6. Try another browser

If the link continues to fail, try opening Claude in a private/incognito browser window.

This can help rule out:

stale cookies
cached login sessions
browser extensions
conflicting authentication sessions

If you're using Claude Desktop, you can also try logging into Claude through the web application to determine whether the problem is account-wide or limited to the desktop application.

What if the Claude Console link is expired?

Claude Console has a similar email-based login process.

When you select Continue with email, Anthropic sends an email containing a secure login link. If the link is opened on another device, Anthropic says the process can instead generate a verification code that you enter on the device where you originally requested the login email. (Anthropic Help Center)

So if you see:

Claude Console

This link has already been used

or:

Claude Console

This link has expired

the recommended approach is to return to the Console login screen and request a fresh email.

If you're using the Console for API development, don't confuse the Console authentication flow with API-key authentication. Anthropic recommends API keys or supported cloud-provider authentication when accessing its services through third-party tools. (Anthropic Help Center)

Could it be a Claude outage?

Yes, sometimes authentication problems can be caused by a broader service issue rather than something on your computer.

This is worth checking if:

a new login link doesn't work
multiple devices have the same problem
different browsers have the same problem
Claude isn't sending login emails
other Claude services are also failing

Anthropic's troubleshooting documentation specifically recommends checking the Claude status page when login problems persist. (Anthropic Help Center)

There have also been community reports of broader Claude authentication incidents. For example, users reported problems with Claude login, OAuth, and other services during a March 2026 incident. (Reddit)

So before spending an hour clearing browser data, it's worth checking whether Claude itself is experiencing an incident.

What if nothing works?

If you've tried a fresh login link, another browser, another device, and the problem continues, the issue may require Anthropic's support team.

Anthropic's current support documentation says users can access support through the Claude interface, with Pro and Max users as well as Team and Enterprise owners and Console admins having access to further Product Support assistance. (Anthropic Help Center)

If you're completely unable to log in, the normal in-product support flow may be difficult to access. In that situation, use Anthropic's official support resources and explain exactly what you're seeing.

Include useful details such as:

Whether you're using Claude, Claude Desktop, or Claude Console
Your operating system
Your browser
Whether the login email arrives
The exact error message
Whether the link was opened on the same device
Whether a new login link produces the same error

Don't send your magic-link URL or other authentication credentials to anyone.

A quick troubleshooting checklist

If you see “This link has expired” or “This link has already been used,” try this:

[ ] Go back to Claude and request a new login link.
[ ] Use the newest email rather than an older one.
[ ] Open the link on the same device where you requested it.
[ ] Don't repeatedly click the same magic link.
[ ] Check spam and junk folders.
[ ] Make sure @mail.anthropic.com isn't being blocked.
[ ] Try an incognito/private browser window.
[ ] Try another browser.
[ ] Try logging into Claude through the web version.
[ ] Check Claude's service status.
[ ] Contact Anthropic Support if the problem persists.

Final thoughts

The “This link has already been used” and “This link has expired” messages can make it look as though something is seriously wrong with your Claude account.

Usually, the first thing to do is much simpler: start a completely new login attempt and use the newest magic link once.

If you're logging into Claude Desktop, pay particular attention to the device you're using. Anthropic's current authentication flow distinguishes between opening the email on the same device and opening it on another device, with the latter potentially requiring a verification code. (Anthropic Help Center)

And if a fresh link still doesn't work across multiple browsers or devices, check Claude's status and consider contacting support.

The key takeaway is:

Don't try to revive an expired magic link. Start a fresh authentication attempt.

For most users, that's the quickest path past the Claude Magic Link error.
