Zhipuai login: signing in to Z.ai surfaces

Reference note: This page is an independent reference on the Zhipuai login process. It does not host a login form and is not affiliated with Zhipu AI. The actual sign-in page is on the upstream BigModel console at the Z.ai platform domain.

Where the Zhipuai login lives

A single account on the BigModel console covers the Z.ai chat surface, the API key console, and the open platform — Zhipuai login is the entry point to all of them.

The Zhipuai login page is hosted on the upstream BigModel console, which is the unified account management surface for the Z.ai platform. A single account registration covers every Z.ai surface: the chat interface, the API key management panel, the billing dashboard, and the project analytics. There is no separate sign-in for the chat surface versus the developer console — the same credentials work across both. International users can register with an international email address; the verification flow sends a code to that address rather than requiring a Chinese mobile number in most markets, though phone verification for SMS-based two-factor authentication requires a phone number that can receive international SMS.

The BigModel console is the canonical management surface for the Zhipuai account. Once signed in, the top-level navigation exposes the chat interface, the API key panel, the billing overview, and the project dashboards. The Zhipu AI open platform reference page on this site covers the console structure in more detail for readers who want to understand what the console contains before registering.

What a signed-in account unlocks

The gap between guest access and signed-in access on the Z.ai platform is substantial — most meaningful workflows require a Zhipuai login.

A signed-in Zhipuai account unlocks persistent conversation history in the chat Z AI surface. Every conversation thread is saved to the account and accessible from the sidebar on any device where the account is signed in. Guest sessions produce no persistent record — when the browser tab closes, the conversation is gone. For any workflow where reviewing prior conversations, continuing a thread across sessions, or sharing a conversation export matters, signing in is a prerequisite rather than an optional convenience.

Beyond conversation history, the signed-in account unlocks the full model picker in the Zhipu AI chat interface. Guest sessions typically default to a single model with no option to switch. Signed-in accounts can select any GLM variant in the current lineup, including the code-specialised variant and the lighter models better suited to quick iteration. The full model picker is one of the most immediately useful features that signing in enables, especially for users who are actively evaluating different model configurations for a specific task.

For developers, the most important feature unlocked by the Zhipuai login is API key generation. The BigModel console, accessible after login, is where API keys are created, labelled, and revoked. Without a signed-in account, there is no path to a valid API key for programmatic access to the GLM model family.

Password recovery

The Zhipuai password recovery flow works through the registered email address or the registered phone number, depending on how the account was originally created.

The Zhipuai login page includes a password recovery option directly below the sign-in fields. Clicking it initiates one of two recovery paths depending on the account creation method. Accounts created with an email address receive a reset link at that address; the link expires after a short window (typically 30 minutes), so the reset should be completed promptly after requesting it. If the original link expires, a fresh one can be requested without any penalty.

Accounts created with a phone number as the primary identifier use SMS verification for recovery. The system sends a six-digit code to the registered phone; entering the code correctly allows setting a new password. This path requires that the phone number remains active and reachable — accounts whose registered phone number has been disconnected or changed without updating the account profile may need to contact the BigModel support channel for account recovery.

For international accounts that registered with an email address during the period when phone verification was optional, email recovery is the reliable path. Phone recovery may produce unexpected behaviour if the account was created before the platform unified phone and email registration into a single flow.

Guest versus signed-in feature comparison

The feature gap between guest and signed-in access is covered clearly in the table below — most workflows that matter require a Zhipuai login.

Guest access is useful for a first-look evaluation: it lets an unfamiliar user test the model's response quality without any registration overhead. The limitation is that nothing from a guest session carries forward. No conversation history, no prompt recall, no model picker, no API access, no billing panel. Teams that want to evaluate the platform seriously for any workflow beyond a one-time curiosity check will exhaust what guest access offers within a few minutes and need to register. The registration process accepts international email addresses and takes under two minutes for accounts that do not require phone-number two-factor authentication.

Common login problems for international users

Three recurring issues account for the majority of Zhipuai login failures for users outside mainland China.

The first and most common is the SMS verification format. When a phone number is required during registration or recovery, the platform expects a full international format including the country dialling code. Entering a number without the country code prefix causes the SMS dispatch to fail silently in some configurations. Adding the full country code — for example, +1 for US numbers, +44 for UK numbers — resolves the issue in most cases.

The second is the interface language default. The Zhipuai login page defaults to Chinese for first-time visitors. There is a language toggle in the upper-right corner of the page that switches the interface to English. Once set, the language preference persists across the account for the management console; the chat surface has a separate language toggle that also defaults to Chinese for new accounts.

The third is legacy BigModel credentials. Engineers who created accounts on the BigModel console under the older branding may find that their credentials do not work on the Z.ai login surface without a password reset. The account itself is still valid — the two surfaces share the same identity backend — but some legacy accounts require a one-time password reset to synchronise with the unified login system. The email recovery path is the correct approach in this case.

Security guidance from NIST on credential management and access control is useful background for teams integrating Zhipuai login into a broader enterprise identity management process.
