I'm not receiving the password reset email

Making a secure password:
When setting a password, it's important for it to be secure and difficult for other people to guess.

To set a secure password, make sure it:
• Is a complex combination of upper and lowercase letters, numbers, and symbols.

• Doesn't use personal information, such as:
- Your nickname or initials.
- The name of a child or pet.
- A birthday or anniversary of you or a loved one.
- Your address.

• Doesn't use typical strings of characters or words, such as:
- Easy to guess words or phrases (e.g. "password" or "iloveyou").
- Consecutive letters or numbers (e.g. "123456" or "abc123").
- Strings that follow the keyboard layout (e.g. "qwerty" or "1q2w3e").

Note: Your password must contain 8-20 non-repeating half-width characters, and be a combination of at least three of the following types: uppercase letters, lowercase letters, numbers, and symbols.

For the best online security, make sure not to recycle passwords, but rather to set and safely manage a different passcode/password for each online service you use.

Making use of software and OS features to manage your passwords is another way to achieve secure password creation and management. You can get a complex password with ease and peace of mind by using a software feature to automatically generate a password.

If you use software to manage your passwords, you can use all different passwords for each service without the burden of remembering them.
