How do I change my login details in Family Tree Builder?

When you download and install Family Tree Builder (FTB) for the first time, you will be asked to register the program.

If you already have an account at, you can use your registered email address and password to log in. This will allow you to sync your family tree to the family sites you have already created on

Also, if you are a Premium or PremiumPlus customer, registering Family Tree Builder with your MyHeritage registered email address will allow you immediate access to the Premium features in Family Tree Builder, such as SmartMatch Merge and Timeline.

So what happens if you already have an account at, but you registered Family Tree Builder with a different email address by mistake (or changed your email address on MyHeritage and now need to change it in Family Tree Builder)?

Here is what you need to do:

1. Open the FTB software on your computer

2. In the upper menu bar click ‘Sync (publishing)’ and select ‘My Sites’:

3. In the window that pops up, click on the ‘Log in as a different member’ link:

There you will be able to enter a different email address and password, or just change your password.
