## Things to Keep in Mind
### Auto-generated passwords
{% hint style="info" %}
**Creating a new user via sync, will auto-generate a password in Memberstack**
{% endhint %}
Whalesync allows you to create new Memberstack members from a synced app. For example, you can create a new member from Airtable :tada:.
When creating a new member in Airtable, Whalesync auto-generates a password for that Member. That new member will need to reset their password to log in.
### Syncing custom fields
{% hint style="info" %}
**To sync custom fields, you will need to create a member in Memberstack with the email "" with values in custom fields.**
{% endhint %}
See :point\_down:for more details

{% endcontent-ref %}
### Default sync delay
{% hint style="info" %}
**If syncing Memberstack and Airtable, we default to a 10-second sync delay from Airtable to Memberstack**
{% endhint %}

{% endcontent-ref %}
### Metadata fields
{% hint style="info" %}
**Metadata fields sync as JSON**
{% endhint %}
We support 2-way syncing of Memberstack Metadata fields as JSON blobs. You can edit the data in those fields as long as they retain the correct JSON format.
## Templates
Copy our Airtable or Notion templates to instantly have a table set up to sync with Memberstack.
