Multiple Zoho One accounts

Multiple Zoho One accounts

Hello. I'm searching for a solution to run multiple organizations under 1 Zoho One account or have a different Zoho One account for each organization and still be able to easily login to each. Currently Zoho One doesn't allow the same email address to be used in more than 1 Zoho One account. If I was to create multiple email addresses (so each team member has a different email address for each organization's Zoho One account), can Zoho Vault keep track of those email addresses and passwords and allow single click sign on to multiple Zoho One accounts in the same browser?
