## Profile management methods

### Get a customer account details
You can use this method to retrieve all information about a customer from Synerise. You can then present that information in the app.

Separately from customer information updates, a customer may want to change their password. The default password policy is:
- Minimum 6 characters
- At least one uppercase letter
- At least one lowercase letter
- At least one digit
- At least one non-alphanumeric character

Passwords are PBKDF2-encrypted.


<div class="admonition admonition-note"><div class="admonition-icon"><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" stroke-width="2.5"><path stroke-linecap="round" stroke-linejoin="round" d="M13 16h-1v-4h-1m1-4h.01M21 12a9 9 0 11-18 0 9 9 0 0118 0z" /></svg></div><div class="admonition-body"><div class="admonition-content">

You can define the password policy in the Synerise platform (`app.synerise.com`). You can find more information about it [here](/docs/settings/tool/iam-for-apps/synerise#password-policy).
