How to access Claude without creating an Anthropic account

Anthropic's strict login requirements

Anthropic does not offer a guest mode for Claude on its official website, desktop app, or mobile applications. Every new user must create an account to access the service, which currently requires signing in via Google, Apple, email, or company SSO. Because there is no dedicated password option, users are directed to one-time email links or third-party identity providers.

Beyond the login itself, the sign-up process includes several mandatory hurdles. Users must provide a phone number capable of receiving SMS text messages, confirm they are located in a supported country, and verify they are at least 18 years old. Anthropic states that phone verification is a mandatory step and there is no way to skip it during the account creation process.

The phone verification system is specifically designed to block certain types of numbers. Anthropic rejects VoIP numbers, Google Voice, landlines, and numbers generated by apps. Additionally, a single phone number can only be used to verify a maximum of three separate Claude accounts. Once a number is linked to an account, it cannot be changed, making it a permanent identifier for that user's profile.

Bypassing the phone check via Duck.ai

For users who want to interact with Claude without providing any personal information, Duck.ai offers a specialized route. This service is DuckDuckGo’s AI chat, which allows users to access popular chatbots like Claude without creating an account. It is designed for anonymity, as it removes metadata like your IP address before the prompt reaches the model provider.

The free tier of Duck.ai specifically serves the Claude Haiku 4.5 model, which is a smaller and faster version of Anthropic's AI. While it is capable of handling summaries and quick rewrites, it is not the same high-end model used for long documents on the official site. DuckDuckGo also ensures that conversations are not recorded or stored by default and are not used to train any models.

There are limitations to this no-login experience, particularly regarding usage and file types. Duck.ai enforces a daily limit on free chats that is not publicly disclosed, and it may trigger early if a VPN or mobile network is detected. While some models on the platform support images and PDFs, spreadsheets are not supported, and PDF uploads are capped at 15 pages for free users.

Native access through Fello AI

Another way to use Claude without an Anthropic account is through the Fello AI app, which is available on Mac, iPhone, and iPad. This service runs Claude inside a native application, meaning users do not need to sign up for an Anthropic account or provide a phone number for SMS verification. It also removes the need for a Fello account, though an optional login can be used to sync data across different devices.

Fello AI positions itself as a multi-model platform where Claude sits alongside other popular AI tools like GPT, Gemini, and Grok. This allows users to switch between different models within the same chat interface. The app provides a premium experience that includes web searching, PDF and Word file reading, and the ability to build Excel sheets or PowerPoint decks.

While Fello AI offers a free tier that allows for a limited number of questions per hour on premium models, it also offers a paid subscription. The full plan costs $11.99 a month or $89.99 a year, billed through Apple ID. This route is specifically designed for users who want the full power of the current Claude models without navigating Anthropic's specific account restrictions.

Risks of unofficial 'no-login' sites

Because the demand for Claude without a login is high, many unofficial websites appear in search results promising free access. These sites are not run by Anthropic and do not fall under any of the company's privacy promises. Users who visit these pages cannot be certain which model they are interacting with, or if the service is actually using Claude at all.

The primary risk with these third-party sites is the lack of transparency regarding data handling. These operators may collect and store your messages, payment information, or email addresses without clear disclosure. Fello AI warns that if a site promising no-login access asks for a payment card, a browser extension, or an email address before letting you chat, it should be closed immediately.

For those seeking a legitimate way to use Claude privately, the options are limited to verified services. Duck.ai is the recommended path for quick, anonymous questions using a smaller model. For those who need the full capabilities of the latest Claude models in a dedicated app environment, using a service like Fello AI provides a verified way to bypass the phone verification requirement.

Technical limitations and geography

Geography remains a significant barrier for users trying to access Claude directly. Anthropic only supports users who are physically located in specific countries, such as the United States, Brazil, France, and Mexico. The system is designed to detect physical location, meaning that using a VPN to appear in a supported region is not a valid way to bypass these restrictions.

The phone number provided during sign-up must also originate from one of the supported countries. This dual requirement of physical location and a local phone number makes it difficult for international users to create official accounts. Because the phone number is used for verification and cannot be changed later, users must ensure they have a permanent, compatible number before starting the process.

For developers and companies, there are alternative ways to integrate Claude into workflows without a standard web login. Claude Code can skip the browser login if a specific environment variable is set with an API key. Furthermore, companies can authenticate through cloud platforms like Amazon Bedrock or Google Cloud, which use corporate cloud accounts instead of individual Anthropic logins.
