Per instructions, below, user is to use Password B, whereas Password A is what successfully logged me in.

@shawnyeager Thanks for the report ... wil recheck for update release v1.6.1
OK I just rechecked with the lastest code for v1.6.1 release ... it is password B for specter login.
Last check before closing the issue: Test on a fresh setuped RaspiBlitz with test v1.6.1 code
OK found some smaller bugs to fix on fnal testing: #1642 .. but Specter looks good now and used all the correct passwordB on tests. Closing this issue for v1.6.1 release.
