Claude Login on Android: Sign In and Sign Out

Find the Official Sign-In Route

For Claude login on Android, start from Claude’s official sign-in page or the official Claude app, then choose the account path that matches how you use Claude. Anthropic’s Claude account login guide documents two sign-in options: Continue with Google and Continue with email. The email path sends a secure login link, while the Google path uses the Google account you select during the flow.

If you are in the Android app and the sign-in screen will not complete, open the official Claude web login in a trusted Android browser and try the same account there. That quickly separates a local app or webview issue from an account identity issue. Use Google when the Claude account belongs to that Google identity. Use the email link when you registered with an email address or when Google account selection is unclear.

Sign In With the Intended Google Account

Continue with Google is fast when Android presents the right identity. It can also create confusion on a phone that carries several accounts. A personal Gmail address, a work profile, a school profile, and a shared-device account can all appear in the Google account picker. If Claude was created with one address and Android selects another, you may land in a blank account, see a different workspace, or think your history has disappeared.

Before tapping through, read the email address shown in the Google picker. If it is not the one tied to your Claude account, back out and choose the intended account. In a browser, you may need to switch Google profiles or sign out of the wrong Google session before starting again. On a managed phone, the work profile and personal profile can keep separate browser states, so make the profile choice part of the check.

After a successful sign-in, confirm the account email, workspace, and plan state inside Claude before assuming anything is missing. Personal Claude access and organization workspace access can differ even when both are reachable from the same device. The account you use on Android should match the account you use on desktop if you expect the same conversations and settings.

Third-party tools should be treated separately. A Claude consumer subscription or Google sign-in does not automatically provide API authentication for another product. If you later configure a compatible model endpoint in FoneClaw, that setup uses separate endpoint and credential fields rather than borrowing the consumer app login.

Complete Email-Link Login

Email-link login is useful when Google sign-in keeps choosing the wrong account or when your Claude account was created with an email address. Choose Continue with email, enter the exact address tied to Claude, and open the secure login link sent to that inbox. If you open the link on the same Android device that requested it, the browser or app completes sign-in for that session.

The two-device flow is different but still official. Anthropic’s login guide says that if you open the login link on another device, Claude provides a verification code. Enter that code on the original device that requested the sign-in. For example, you can request login on your Android phone, open email on a laptop, and type the displayed code back into the Android sign-in screen.

If the link does not arrive, first verify the address. A typo, alias, organization routing rule, or old account address can make the email look missing. Then check spam, promotions, quarantine, and corporate mail filters. If the mailbox is managed by a company or school, delivery rules may block or delay the message.

Use one fresh login attempt at a time. Repeatedly requesting links can leave you with several emails and no clear idea which one belongs to the current Android request. The reliable path is simple: request the link, open the newest relevant message, complete the same-device flow or enter the cross-device code, then verify the Claude account email after sign-in.

Diagnose Login Loops and Missing Email

When Claude login is not working, diagnose the visible symptom before changing broad account settings. The first question is identity: did you choose the same Google email or email-link address used for Claude? If the account is wrong, clearing app data or reinstalling will not recover the expected history.

Next, check the official app and device path. If the Claude app listing is unavailable because of region, device, profile, or Android version, use the official web login in a trusted browser rather than installing an unofficial package. This keeps the account flow on an official surface while you confirm whether the issue is app availability or authentication.

Then reduce local interference. Browser cookies, private mode, aggressive privacy settings, managed webviews, blocked pop-ups, VPNs, and extensions can interrupt the handoff from Google or from an email link back to Claude. A trusted browser with normal cookies enabled is a good narrow test. If that works, focus on the local app or browser environment before changing the Claude account itself.

If the account and local path look right, check Claude’s official status page before repeating the same attempt. A service issue can look like a local login loop. If you contact support, include the sign-in method, error text, device model, Android version, region, and whether the same account works on web. Do not include login links, verification codes, API keys, or other secrets.

End One Session or Sign Out Across Devices

After an account mix-up, a lost phone, or a shared-device mistake, session review is often more useful than another reinstall. Anthropic’s active-session management guide says Claude web Settings > Account lists active sessions with device or browser information, approximate location based on IP address, updated time, and a marker for the current session.

Use that page to terminate one session when you recognize a stale browser, old phone, or desktop you no longer use. Select the session menu, choose Terminate, and confirm. Approximate location is a signal, not proof of unauthorized access; mobile networks, VPNs, corporate routing, and travel can all make the location look different from where you are sitting.

For a broader reset, use Anthropic’s global logout guidance. Global logout is available from Claude web Settings > Account and is not currently available inside the native Android or iOS apps. Anthropic says the sign-out covers browsers, mobile apps, and desktop apps. After global logout, sign back in where needed using Continue with Google or the email-link flow.

The same guide says Claude web sessions last 28 days and refresh with activity. Treat that as a web-session rule, not a guarantee for every app surface or organization policy. It explains why a laptop browser can stay active while Android asks you to authenticate again. If your goal is only to sign out of one old device, terminate that session. If your goal is a clean restart everywhere, use global logout and then reopen only the sessions you actually need.

Claude Code authorization has separate settings, so handle it from the dedicated Claude Code authorization controls rather than Android session controls. For Android account access, the useful sequence is to reach the right Claude account, review active sessions on the web, sign out stale devices, and reauthenticate only where you still want access.

Keep Sessions and API Credentials Separate

Session logout and API-key revocation solve different problems. Signing out of Claude sessions ends consumer app and web access on devices. It does not revoke API keys used by developer tools, scripts, servers, or third-party integrations. If an API key is exposed, use the provider console for that key and rotate it through the service that issued it.

Anthropic’s September 2026 threat intelligence report describes theft of AI API keys from customer environments and subsequent misuse. In the cited actor case, Anthropic says its own systems were not compromised. The Android takeaway is narrow: a login loop is not evidence of compromise, and global logout is not API-key cleanup.

This boundary also matters for FoneClaw. A Claude consumer login may get you into Claude’s own app or web product. A compatible model endpoint configured in FoneClaw is a separate model setup. Keep account sessions, API credentials, and phone-agent permissions in their own lanes so troubleshooting stays simple.

Choose the Next Android Task

Once Claude sign-in is working, decide what you actually want to do on Android. If the task is Claude-specific mobile use, Claude Cowork on Android: Mobile Chat, Cowork Workflows, and Phone Actions gives the broader Claude mobile workflow. If the problem continues after sign-in because a model service is unavailable or slow, Android AI Assistant Model Outage: Retry, Switch Models, and Resume Safely explains retry, model switching, and safe resumption.

FoneClaw is the route when you want a governed Android phone action after account access is settled. You can start with FoneClaw’s free default model, or configure a compatible endpoint with an API Base URL and API Key. In that workflow, the configured model reasons and plans inside FoneClaw, while enabled Android tools carry out supported actions under current permissions and approval policy.

A good first phone-side check is reversible and visible: ask FoneClaw to check device time, inspect permission status, or perform another supported low-risk task with a clear result. Current model management makes configured endpoints easier to edit, but a Claude consumer subscription should not be treated as an API key or as automatic FoneClaw access. For setup details, use Connect an AI Model API to an Android Phone Agent in FoneClaw.

You can review supported capability areas on FoneClaw Features and current installation options on FoneClaw Download. The clean path is: finish Claude login, sign out unwanted sessions if needed, then choose whether the next step belongs in Claude itself, a model endpoint setup, or a FoneClaw Android task.
