A2 Passwords

In this new age of GPU resources and AI agents account security is more important than ever. To that end, Andromeda 2 has a set of password policies to ensure researchers are settings a strong password for their access to the cluster.

  • Your last 100 passwords cannot be reused
  • 4 Character classes are required (Upper and low case, numeric and special)
  • Min password length is 12 characters
  • A maximum of 3 repeated (aaa) characters in a row
  • A maximum of 3 sequential (abc) characters
  • Passwords cannot contain your login, first name, last name, etc…

*NEVER SHARE YOUR PASSWORD WITH ANYONE!!!
**ONLY YOU ARE ALLOWED TO LOG INTO THE CLUSTER WITH YOUR ACCOUNT!

When an account is first created on A2 the account owner is given a temporary password for an initial login where they’ll need to set a long term password to have full access to the cluster’s resources.

Password Tips

  • Longer is better
    • The following would make a pretty good password (don’t actually use it as your pw!!!):
      My dog’s the only 1 for me =)
    • That phrase has all 5 character class; Upper, lower, numeric, punctuation and special.
  • 3 repeated and/or 3 sequential characters might get your password rejected
    • There’s an obscure rule in the character class counting process for our identity management that deducts a class if the new password you enter meets, but doesn’t exceed, the repeat and/or sequential limits.
    • The following will fail:
      SayfPW999&&&
    • These will also fail, because they still meet 2 of the limits:
      SayfPW999&&&!
      SayfPW999&&&!@
      SayfPW999&&&!@6
    • This will succeed:
      SayfPW996&&&
