# Signing in with your PornTok account

> One account works on both sites, and links from PornTok can sign you in automatically.

Sinfully is made by the team behind [PornTok](https://porntok.io), and the two sites share one account system.

## Use the same details

If you have a PornTok account, sign in here with the same email address and password, or the same Google account. There's nothing to set up.

## Arriving from PornTok

If you're signed in on PornTok and follow a link to Sinfully, you'll usually arrive already signed in. The link carries a one-time pass that works once, for a few minutes, and only for you. If it has expired, just sign in as usual.

## What's shared, and what isn't

- **Shared:** your email address, username and password.
- **Not shared:** your companion chats, memories, photos, videos, Sins and plan stay on Sinfully. Nothing you do here shows up on PornTok.

## Changing your password or email

Because it's one account, changing your password or email address on either site changes it on both.

## Deleting your account

Deleting your account closes it on both sites. To remove only your Sinfully data, see [Deleting your account](https://sinfully.ai/help/delete-account).
