# supabase auth refresh token not found: session expiry handling

## TL;DR

The refresh token is gone: expired, revoked, or never persisted, so the session cannot renew. Treat it as a signed-out state: clear local session and route to login. Also fix the cause: persist refresh tokens reliably and do not let them expire silently.

```text
AuthApiError: refresh token not found
```

## Steps

1. Handle it as signed-out: clear the local session and redirect to login.
   Expected: The app recovers gracefully.

2. Check refresh-token persistence: is it stored reliably (httpOnly cookie or secure storage) and sent on refresh?
   Expected: The storage path is verified.

3. Check the refresh token's lifetime settings in Supabase; expired tokens cannot refresh.
   Expected: The lifetime is known.

4. Fix the persistence or lifetime issue found above.
   Expected: Refresh works for live sessions.

5. Distinguish this from network errors in the client: only this error means re-login.
   Expected: The UX routes correctly.

## When to use

- Supabase sessions die with refresh-token-not-found
- after storage changes
- refresh lifetimes were adjusted

## When not to use

- the error is intermittent (check the network first)
- the token exists but is rejected (different error)
- using a custom auth backend (Supabase-specific handling)

## Tool compatibility

- Supabase Auth
- GoTrue

## Variant phrasings

- "supabase refresh token not found"
- "supabase session expiry handling"
- "refresh token not found supabase auth"

## Why it happens

Refresh tokens are the durable half of the session; when they vanish, there is nothing to renew with. Causes range from aggressive storage clearing to expired lifetimes to revoked sessions. The client must treat it as signed-out, because from the server's perspective the session is over.

## Edge cases

- clearing site data wipes refresh tokens; that is working as designed
- the re-login UX should preserve the user's intended destination
- server-side session revocation is a feature; handle it, do not fight it
