Creating your account
You usually get an invitation from your care provider or your lab. This is how you create your account.
Last checked on October 21, 2026
Step by step
- Open the invitation email and click the button.
- Choose a password, or choose “Continue with Google”.
- Set up the second step you will use to sign in from now on.
- Read the terms and click “Agree and continue”.
Changing it later
You manage your password and your second step yourself: open “Profile & privacy” in the menu and, next to “Password and second step”, choose “Manage”.
My invitation link doesn't work
What the message means and what to do.
What does the message say?
- “This link has expired.” Synapse sends you a new email by itself. Check your inbox within a few minutes, including spam.
- “This link no longer works”: if you already created your account, sign in. Otherwise, ask the person who invited you for a new link.
- “This invitation was withdrawn”: contact the person who invited you.
- “Your account is already active”: sign in to continue.
- “This email address is already in use”: sign in with that account, or ask to be invited at another address.
- “That didn't work just now”: your invitation stays valid. Try again in a few minutes.
- “We couldn't create your account”: email us at info@synapse-lifestyle.com with the support code you see.
The link is for another account
If you are signed in with a different email address from the one in the link, Synapse asks you to sign in with the address of the link.
Language, theme and emails
You set your language, your theme and which emails you get yourself.
Language and theme
Under “Profile & privacy” you'll find “Preferences”:
- “Language”: the language of the app and your report.
- “Theme”: “Light”, “Dark” or “System”.
Emails
With “Emails from Synapse” you choose whether we may also send you emails you don't strictly need, such as a reminder. Emails you do need, such as when your report is ready, always reach you. You can also unsubscribe through the unsubscribe link in an email from Synapse.
Giving feedback
Missing something, or have an idea? Choose “Feedback” in the menu.

How it works
- Click “Messages” at the top to open your messages.
- When there are new messages, the bell shows it.
- If it says “Nothing new”, nothing is waiting for you.
