Our password requirements are as follows:

• Minimum length of 15 characters.
• Minimum of 8 unique characters.
• Must not be one of the 100,000 most commonly-used passwords.

You are free to use any characters you like, including spaces and emojis 😎🐶❤️

A password manager will easily generate secure passwords that satisfy the above requirements. Alternatively, consider using a passphrase rather than a password.
