When signing up for Reclaim using your Google account, Reclaim will use that account's email address as your main login and calendar for your Reclaim account. However, you can also connect other emails to your Reclaim account via Calendar Sync or Connected Calendars and login using any of those emails.
In other words, your Reclaim account can have multiple emails, but only one can be set as your main email / calendar, and the others are secondary used for things like syncing calendars or telling Reclaim which calendars to consider your availability from.
Using the same email on multiple Reclaim accounts
An email address can only be set as the main account email for a single Reclaim account. It can be associated with multiple Reclaim accounts, but can't be the main on more than one. We generally do not recommend using multiple Reclaim accounts.
If an email address is associated with more than one Reclaim account, logging in with that email will automatically log you into the account where that email is set as the main account email.
If an email is used in more than one Reclaim account, but isn't a main login for any Reclaim account, logging in using that email will prompt you to create a new account.
For example, if the email [email protected] is used as a secondary email in Accounts A and B, but isn't set as main anywhere else, logging in with [email protected] will prompt you to create a third account.
