The Account settings tab is where you manage your security and passwords.

Note
If you are using Google SSO to login, you will not see an option to change your password. Instead, you'll have to log out of your account and request a password reset link.

From Settings:
When adding an additional email address to your Asana account, note that:
You can add multiple email addresses to your Asana account. With multiple email addresses associated with your account you can:
When you add a second email address to your Asana account, you will be asked to verify your identity by re-authenticating your Asana account. This means that you will have to re-login with the existing email address in order to add a new one.
Note
If you use the Login with Google feature, you will instead be required to verify your Google account. A pop up window will appear to log into Google, enter the credentials for the email address currently associated to your Asana account to initiate the process.
Contact our Support team using the Asana Support Bot if you have any issues when adding a new email address to your account.
You can only remove an email address if you already have more than one email address associated with your account, if you no longer use that email address or if it belongs to someone else.
To remove an email, navigate to the Account tab and click Remove.
Leaving an Organization will remove your corporate email address associated with it from your account.
Members of organizations with SAML or Google SSO enabled will not see an option to change their password.
Note
If you don't remember your password, an alternate option would be to request a password reset link sent to your email address from the login page. You will need to log out of your account to get back to the login page.
NB: Only deactivate your individual Asana account if you no longer wish to use Asana. Deactivating an account is permanent and cannot be undone. You can deactivate your account via the Account tab of Settings
Once you deactivate your account, you will no longer have access to any data in the account. If you would like to use Asana in the future, you will need to sign up for a new account.
Note
Deactivation only deactivates your individual Asana account. The organizations and workspaces you belong to are shared spaces and will continue to exist.
Account deletion is different from deactivation and permanently removes your account and data from Asana. For complete instructions on how to delete your account, including important considerations and step-by-step guidance, please see our dedicated article: Delete your Asana account.
If you're unsure which option is right for you:
Choose deactivation if you might return to Asana in the future or want to preserve your data.
Choose deletion only if you're certain you won't need your Asana data again and want it permanently removed.
