Based on the search results, here's what I found about Supabase signUp, mailer_autoconfirm, session cookies, and related authentication concepts:

## signUp Method

The PKCE flow cannot be used when autoconfirm is enabled. When it comes to email confirmation behavior, if Confirm email is enabled, a user is returned but session is null. If Confirm email is disabled, both a user and a session are returned.

## Mailer Autoconfirm Configuration

GOTRUE_MAILER_AUTOCONFIRM set to false can be configured to disable automatic email confirmations, while SMTP params needs to be there for ENABLE_EMAIL_AUTOCONFIRM=true to work in self-hosted deployments.

When autoconfirm is enabled, anonymous users can be converted without the verification step.

## Session and Cookies

When using cookies to store access and refresh tokens, make sure that the Expires or Max-Age attributes of the cookies is set to a timestamp very far into the future. Browsers will clear the cookies, but the session will remain active in Supabase Auth. Therefore it's best to let Supabase Auth control the validity of these tokens and instruct the browser to always store the cookies indefinitely.

Additionally, anonymous users receive standard sessions with refresh tokens.

Based on the search results, I can provide you with information about how Supabase's `signUp` method handles sessions when autoconfirm is enabled:

When Confirm email is enabled, a user is returned but session is null. If Confirm email is disabled, both a user and a session are returned.

This means that autoconfirm (email confirmation disabled) allows the `signUp` method to return a session immediately after signup. When autoconfirm is **enabled** (meaning email confirmation is required), no session is returned.

The key distinction is:
- **Autoconfirm disabled (email confirmation required)**: Returns user but `session` is `null`
- **Autoconfirm enabled (no email confirmation required)**: Returns both user and `session`

This behavior is consistent across Supabase's various SDK implementations (JavaScript, Swift, Flutter/Dart, and others).

Based on the search results, I found several relevant discussions about the `@supabase/ssr` signUp cookie not setting issue:

## Common Issues Found

The auth-token cookie is not setting properly - when logging in twice, it sets on the second attempt, but the first time only the auth-token-code-verifier cookie is set.

After migrating to @supabase/ssr, users found that cookies being set are HTTP-only, which causes users to not be signed in after signup form submission, profile creation, and redirection because the SupabaseBrowserClient can't access those cookies to create a Session.

## Known Solutions

By default the cookies are not HTTP-only in the latest version as this was a bug that got fixed - you should check you are using the latest version of the @supabase/ssr package and remove your node_modules before reinstalling if your version number looks like the latest.

## Route Prefetching Issue

When you use route prefetching in Next.js using Link components or Router.push() APIs, they can send server-side requests before the browser processes the access and refresh tokens, meaning those requests may not have any cookies set. To improve experience, you should redirect users to one specific page after sign-in that does not include any route prefetching from Next.js, and once the Supabase client library in the browser has obtained the tokens, you can send users to any pages that use prefetching.

The GitHub issues linked in the search results provide additional context and discussions around this problem that may help you troubleshoot further.

# SignUp Return Value with Autoconfirm Enabled

According to the documentation, when autoconfirm is enabled, the `signUp()` method returns both a user and a session:

"If **Confirm email** is disabled, both a `user` and a `session` are returned."

Since autoconfirm functionality disables email confirmation requirements, the method will provide you with both the newly created user object and an active session for immediate authentication.

Based on the web search results, I found several issues related to `@supabase/ssr` and session cookie problems during sign-up:

## Key Issues Found

### 1. **Auth-Token Cookie Not Setting on First Sign-Up**

The auth-token cookie is not setting properly on the first sign-up—only the `sb-__-auth-token-code-verifier` cookie is set initially, and the full auth cookie only appears on a second login.

### 2. **Cookie Setting Limitations with Next.js**

There's an issue with how cookies are being set, as only a single Set-Cookie header can be set with Next.js, which appears to be a constant limitation.

### 3. **Session Cookie Format Issues**

Despite following current best practices and using the latest versions of @supabase/ssr and @supabase/supabase-js in a Next.js 14+ App Router project, the session cookie is always set in the legacy base64 format, even with `cookieEncoding: 'none'` configured.

### 4. **Cookie Options Being Ignored**

The createServerClient method ignores the cookieOptions property maxAge, and the config.toml property jwt_expiry is also ignored when setting the auth cookie expiry.

### 5. **Browser Cookie Setting Problems**

After `signInWithPassword`, a session object is successfully returned but the browser doesn't set any auth cookie, and navigating to protected routes results in an infinite redirect loop because the middleware sees no cookie.

These issues appear to stem from timing problems with cookie handling, Next.js limitations with the Set-Cookie header, and potential configuration conflicts between the SSR package and Next.js App Router.

# Supabase SSR Cookie Setting Issue

## The Problem

When users sign up or log in using the Supabase SSR package with Next.js, authentication cookies aren't being set properly on the first attempt. Specifically, only `sb-___-auth-token-code-verifier` gets set initially, while the critical `sb-___-auth-token` cookie appears only after a second login.

## Root Cause

The issue stems from how cookies are being managed in the Next.js middleware. The problematic approach involves setting cookies on both the request and creating a new response object:

> "request.cookies.set({...}); response = NextResponse.next({...}); response.cookies.set({...})"

This dual-setting approach creates conflicts in how Next.js handles the `Set-Cookie` headers.

## The Solution

Remove the request cookie manipulation entirely and set cookies only on the response object:

> "let response = NextResponse.next({...}); set(name: string, value: string, options) { response.cookies.set(name, value, options); }"

This streamlined approach ensures cookies are properly persisted after authentication, eliminating the need for users to log in twice to complete the session establishment.

Perfect! Now I have comprehensive information. Let me compile the findings.

## Summary of Findings

Based on my research into Supabase documentation and known issues, here are the answers to your questions:

### 1. **Does `signUp()` return a valid session when autoconfirm is enabled?**

**YES** — According to Supabase documentation, when autoconfirm is enabled (email confirmation is **disabled**), the `signUp()` method returns **both** a user object **and** a valid session. This is the key distinction:
- **Autoconfirm enabled** (no email confirmation required): Returns both `user` and `session`
- **Autoconfirm disabled** (email confirmation required): Returns `user` but `session` is `null`

### 2. **Is there a known issue where the session/user is returned but cookies aren't properly set?**

**YES** — This is a well-documented issue in the @supabase/ssr package. The problem manifests as:
- **Timing issue**: The auth-token cookie (`sb-___-auth-token`) is not set on the first sign-up attempt; it only appears after a second login
- **Dual cookie-setting conflict**: The root cause is that cookies are being set on both the request object AND the response object simultaneously, creating conflicts in how Next.js handles Set-Cookie headers
- **Solution**: Remove request-level cookie manipulation and set cookies only on the response object

### 3. **Any known bugs with `@supabase/ssr` related to signUp and cookie setting?**

**YES** — Several known issues exist:
- **Issue #36 (SSR repo)**: "Cookies not setting properly" after signUp/login
- **Issue #40**: cookieOptions `maxAge` configuration is ignored by the `createServerClient` method
- **Issue #107**: AuthSessionMissingError occurs despite valid cookies being present
- **Discussion #35553**: Session cookies are always set in legacy base64 format even when configured otherwise
- **Redirect timing problem**: Redirects can happen before cookies are fully set due to timing race conditions

### Project Version

**Your project uses `@supabase/ssr` version `0.8.0`** (as specified in package.json)
