Password splitting for saved passwords

The selected alphabet determines how the generated password itself is written. The optional Password split setting does not change that generated password and does not change the alphabet. It only changes how very long passwords are stored in the recent passwords list when saving recent passwords is enabled.

When password splitting is enabled, the application divides a long generated password into multiple shorter saved entries using the configured split length. Characters are distributed round-robin between the saved entries, so each saved part still comes from the original generated password. The split length can be configured in Options from 1 to 32 characters.

The split is not a simple cut into consecutive blocks. If a generated password abcdefgh1234 is split into two saved entries, the result is aceg13 and bdfh24: the first saved entry receives characters 1, 3, 5, 7, 9, and 11, while the second receives characters 2, 4, 6, 8, 10, and 12. More generally, characters are assigned every k-th position, where k is the number of saved entries.

This matters when a password is built from several different entropy sources. If one source had a small non-uniform bias, round-robin splitting helps avoid concentrating that bias in just one saved password part.
