When you create an account with Coalition you will be asked to create a strong password. In practice, this typically means a password with at least 10 characters (although more may be required depending on what password you enter). Behind the scenes, Coalition uses mathematical algorithms to ensure that your password is "sufficiently hard to guess." A visual password strength meter is available to help you with this process.
The easiest way to generate strong passwords is to use a password manager such as Lastpass, 1Password, or Dashlane. Coalition allows all ASCII characters and very long passwords for those who generate or use them.
If you don't use a password manager (you should!), no need to stress. Instead of trying to remember an incredibly complex password with all sorts of special characters and numbers, try piecing together 4 or 5 random words that you'll easily remember. It's that easy!
