We use firstname.lastname for staff and for students we use - first two letters of first name, first three letters of last, and a number (counter). I will not be as concerned about username length as I would be about password length though. For us, the username is also part of the email addresses. This simplifies the number of different information related to logon that our users will have to remember. We focus on password length and password enforcement and are looking at multi-factor authentication, to bolster authentication security. *Wole Akpose* *Morgan State University * * * On Fri, Aug 16, 2013 at 10:58 AM, Bristol, Gary L. <gbristol () ou edu> wrote:
We currently have ours set to 8 The first four letters of the persons last name and then a randomly generated 4 digits. If a person only has three or two letters in their last name then we use that, but considering the combinations available this seemed to be a good solution for us.

We’ve currently got a maximum length of 8, and given that our plan is to never reuse netIDs, that maximum causes challenges to maintaining uniqueness and having reasonable netIDs without embedded numerals. We’re considering increasing that to 24 characters.**** ** ** What maximum length do you have for netIDs?**** ** ** What is the maximum username length supported in most systems? Some cursory web searches gave me these numbers: **** Windows 256**** Linux 32**** Oracle 30**** MySQL 16**** SQL Server 128**** ** ** Kevin Shalla**** Academic and Enrollment Services**** University of Illinois at Chicago**** ** **
