To the best of our knowledge all characters, including special characters, work fine in SpiderOak ONE, Groups, and Enterprise. Our Quality Assurance team has spent quite a bit of time verifying this, and to date have tested password creation and use up to 80 characters, including special characters. We have received scattered but unreproducible reports of longer passwords or particular characters causing problems on particular platforms. We suspect Unicode errors in the affected users' operating systems, browsers, clipboards, or password managers, but again we have been unable to reproduce any of this.
