# Sign in and account settings

> Sign in to PostOnce with Google or an email code, fix sign-in problems, choose which emails you receive, set your timezone, and change your account email.

## Sign in

PostOnce has no password. Sign in at [postonce.to/signin](https://postonce.to/signin) with:

* **Continue with Google**, or
* **Continue with email**: enter your email and type the 6-digit code from the email, or click **Verify on this device** in the email.

Codes and links expire after 10 minutes and work once. Signing in with an email that has no account creates a new one.

### Sign-in problems

| Message | What to do |
| - | - |
| "That code is incorrect or expired. Check the email or request a new code." | Click **Send a new code** (available after 60 seconds) and use the newest email. |
| "Too many sign-in attempts. Please wait a minute and try again." | Wait a minute, then try again. |
| "This sign-in has expired" | Go back to the sign-in page and request a new email. |
| No email arrived | Check spam and promotions, then click **Send a new code**. |

If you signed up with Google, use **Continue with Google** again.

## Email notifications

Under [Settings › Email notifications](https://postonce.to/dashboard/preferences), choose which emails you get:

* **Successful posts**: when a post publishes to every selected platform.
* **Failed posts**: when one or more platforms fail.
* **Destination suggestions**: ideas for other platforms in success emails.

Account reconnection alerts are always sent, because they keep your workflows running. Changes save automatically.

## Timezone

PostOnce uses your browser's timezone for scheduled posts and the calendar. Workflow schedules have their own **Timezone** setting under **Settings › Publish**, so a workflow can publish in another timezone.

## Change your account email

Changing the email on your account isn't available in the app yet. Email [support@postonce.to](mailto:support@postonce.to) from your current address with the new one.

## Sign out

Click your name at the bottom of the sidebar, then **Logout**.

## Still stuck?

Search this help center with <kbd>⌘</kbd> <kbd>K</kbd>, or email [support@postonce.to](mailto:support@postonce.to) from the address you use for PostOnce. Include the platform, the approximate time, and the exact message you saw. Never send passwords, access tokens, API keys, or card details.
