WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
I don't have any bare displays, but some of the I2C backpack displays I have wouldn't work with the stock library. I finally found one here that worked reliably with a range of displays, but that won't solve your problem as it's all I2C and not nibble-mode writes.
