No — each Anima account needs its own unique email address, both to verify your identity and to keep information from your GP practice secure. If you share an email address with your partner, here are three ways to set up separate accounts:
Create a new email address for one of you. Any free provider works — Gmail, Outlook, Yahoo Mail, iCloud, and so on.
Use a Gmail "+" alias, if you have one. Gmail lets you add "+anything" before the @ symbol, and messages still land in the same inbox. For example, if your address is [email protected], John could register with [email protected] and Mary with [email protected]. You'll just need to remember which version you used when logging in — no changes to your inbox needed.
Add one partner as a dependant. One of you registers as the primary account holder and adds the other as a dependant, so you can submit requests on their behalf. You will need to ask your GP surgery to do this one for you.
