Worse is managing to type your password and confirm password identically incorrectly. It takes the same 15 minutes, but also 15 minutes of not being able to believe it.
Last September I installed Debian 12 in my laptop with an encrypted LVM. Then I tried to add a secondary SSD, also as an encrypted volume, by following some random tutorial I found (spare me, it was my first time fiddling around with an encrypted installation). The next thing I remember is that I was in an initramfs shell trying to fix the boot process 😅🤣. Since I was running low on patience (and it was like 3 AM) I simply decided to nuke the install and start again. Eventually I was able to configure the SSD correctly, but this event reminded me how easily is to brick your system if you're not careful enough. Fun times.
