Sign up, sign in, look after your password, keep your profile up to date, and delete or restore your account.

You can sign up on the web or in the iPhone and Android app. Either way you start a 14-day free trial with no credit card needed.
The same rule applies whenever you set a password: signing up, resetting it, or changing it. Passwords you already have keep working.
| Message | What to do |
|---|---|
| “Use at least 8 characters. 15 or more is best.” | Make it longer. |
| “Use 64 characters or fewer.” | Make it shorter. |
| “That's too long once emoji and accented letters are counted. Try a shorter one.” | Emoji and accented letters take more room behind the scenes. Use fewer of them, or a shorter password. |
| “That password is too common. Choose one that's harder to guess.” | Pick something less predictable, such as a few unrelated words. |
| “Don't use "Chronos" or your email in your password.” | Take out “Chronos” and any part of your email address. |
Each link works once, and asking for a new one cancels the earlier links. If the page says Link expired, choose Request new link.
On the web, open Settings › Account. Under Password, enter your Current Password, your New Password and Confirm New Password, then choose Change password. In the app, go to Settings › More settings on the web to reach the same page.
Changing or resetting your password doesn't sign out devices that are already signed in. To be sure, sign out on each of them.
Deleting removes your account and everything in it, including tasks, events, projects, docs, lists, habits and journal, on the web and in the app. You're signed out and your subscription is cancelled straight away, so you won't be charged again (see Plans & Billing).
When you delete your own account, we keep an encrypted copy for 30 days in case you change your mind.
After 30 days the copy is deleted for good and can't be recovered. You can still sign up with the same email, but you'll start with a new account.
