# Sign In & Your Account

## You can start without an account

Twistly works the moment you open it — your free presentations are available right away, tied to the device you're using. Signing in becomes required only when you purchase a plan.

## Sign-in options

* **Microsoft account**
* **Google account**
* **Email** — enter your email address and confirm with a **6-digit code** we send you. No password needed.

There are no passwords and no separate registration step: whichever option you choose, your Twistly account is created automatically the first time you sign in. Microsoft and Google sign-in opens in a popup window — if nothing appears, check that your browser or PowerPoint isn't blocking popups.

{% hint style="info" %}
Your Twistly sign-in is **independent of the account PowerPoint itself is signed into**. If you have a paid plan, sign in inside the add-in with the exact email you used at purchase — even if PowerPoint is signed in with a different work or school account. It doesn't need to be a Microsoft account.
{% endhint %}

## What signing in gives you

* Your plan and remaining free presentations follow you **across devices** — sign in on another computer and everything is there.
* Anything you used before signing in on this device (including your remaining free presentations) **carries over** to your account. You don't lose your free balance by signing in.

## Good to know

* **Sessions renew automatically** — you won't be asked to sign in again under normal use.
* **Email code not arriving?** It can take a few minutes — check the Spam and Promotions folders. Each code works once; if it expired, request a new one.
* **Asked to sign in repeatedly?** This usually happens when more than one Twistly account has been used on the same device. Sign in with the account that holds your plan.
* **Purchases require sign-in.** If you start a purchase while signed out, Twistly asks you to sign in first and then continues to checkout automatically.
* **Signing out** is available from the add-in's settings. It doesn't affect your presentations — they're your PowerPoint files.
* **New computer?** There's nothing to transfer or restore — install the add-in and sign in with the same email. Your plan follows your account.
* **Changed email address?** (left a job, switched accounts) [Contact us](/help/contact-us.md) and we can move your subscription to your new email.
