Users of membership sites often have and use a membership number. Yet WordPress uses alpha numeric string for usernames for logging in. Why not use both by using the <a href="http://lhero.org/plugins/lh-membership-numbers/" rel="nofollow ugc">LH Membership Number plugin</a>.
LH Membership Numbers allows a user to login by typing in their membership number. Their membership number is the unique user ID that every user is assigned in the database. Optionally administrators can assign a prefix to the membership number (eg for my sports league <a href="https://princesparktouch.com/" rel="nofollow ugc">princesparktouch.com</a> it is PPT). That prefix can make the number far more unique (globally).

Don't be f-wit like bgtbbox (the last reviewer), read what it does and if you don't think it works a specified put something in the support forum and I'll look at it.

Works perfectly
