SamuraiSafe on iOS and macOS now supports password history (retaining previously saved passwords). When enabled, the limit specified in Settings/Preferences indicates the maximum number of previous passwords to be retained for an entry. You can also create a custom limit for a particular entry.
Enabling of the Password History feature requires a password safe file format upgrade. This is unfortunate, and I have taken steps to ensure this shouldn’t be required again. If the Password History feature is of no interest - there is no need to migrate your password safes.
Once you enable Upgrade Safe on Open/Create in Password History Settings/Preferences, and you open an old (V1) format safe, you will be prompted to upgrade to the new (V2) format. This is a quick and safe operation and doesn’t involve any decryption/encryption of entries. A backup copy of the old version of the safe is retained automatically for iOS and macOS iCloud safes and may manually be saved for non iCloud macOS safes.
The backup copy is a precaution. Once you are satisfied the upgrade was successfull and you have opened the upgraded safe on all your devices, feel free to remove the backup.
New versions of SamuraiSafe support both old and new safe file formats, however if you open a new (V2) format safe with an old version of SamuraiSafe you will get one of the following errors:
Upgrading SamuraiSafe to the latest version will resolve the open file error.
If for some reason you are unable to update all your devices or you wish to stay with the old safe file format, you may revert a new (V2) format safe to the old (V1) format.
You need to open the safe in order to perform this operation, then select Revert to SamuraiSafe V1 (under the File menu on macOS and under the Group view Settings icon on iOS). Note that any existing password history will become permanently inaccessible.
Turning off the
Upgrade Safe on Open/Create Password History Setting will stop SamuraiSafe
from prompting to upgrade old safes. This setting also governs whether newly created safes
are new or old file format.
