Similarly, the morning of May 21 a had a BRX that sent its last email. It was the only site I still had on Gmail. For this site I elected to create their own Brevo account, as I didn't need the volume going through my own account. While I have it working now, It wasn't as easy as my other sites were. Along the way, I thought it might be useful to create site specific SMTP keys, instead of using the same master password for all. However, that creates a 90 character password, which is how my question came up earlier. So, back to using the same shorter password for all. Not sure why the master password is shorter than the device specific, but hey, it works again.
