Two-factor authentification, in order to increase the security on World of Potter.
Here's one resource that might be helpful, if the development team decides to implement it.
I do realize this may be a duplicate of this idea, but I'm not exactly sure whether they meant the same thing.
Why use Two-Factor Authentication? (From authy.com)
Relying on just usernames and passwords to secure your online accounts
is no longer considered safe. Data breaches occur daily and hackers are
always inventing new ways to take over your accounts. Protect yourself
by enabling two-factor authentication (2FA). This blocks anyone using
your stolen data by verifying your identity through your device. Enable
2FA now to protect your accounts online.
