It may be a good idea to change your password from time to time.
To do this, click the main menu in the top right corner and choose My profile.
On the My Profile page you can change your data. E.g. email and phone no.
In the bottom left corner, click Change password
After this, you first enter your previous code (the code you have just used to login).
The new code must be entered twice to ensure that you enter it correctly.
Finish and update the code by clicking Save
