i couldn't get one token code to work for multiple logins.

What is your procedure for getting all 5 to work on the same code? Are they all on the same battle.net?

1. start 5 copies
2. login to see 5 authenticator prompts
3. manually apply the same code via multiplexer

1. manually key in code
2. start single copy
3. login to see authenticator prompt
4. apply code
5. loop 2 until all logged in
