A surrogate key is frequently a sequential number (e.g. a Sybase or SQL Server "identity column", a PostgreSQL or Informix serial, an Oracle or SQL Server SEQUENCE or a column defined with AUTO_INCREMENT in MySQL). Some databases provide UUID/GUID as a possible data type for surrogate keys (e.g. PostgreSQL UUID [3] or SQL Server ...
OTP generation with integrated serial number is now also better supported (in PAP). Starting with this version and if activated, the prefix PIN is also needed when using a scratch password. MULTIOTP_PATH environment variable is now supported in order to define where is the root of multiotp (if a specific implementation cannot detect correctly ...
Note (3): "For other than InnoDB storage engines, MySQL Server parses and ignores the FOREIGN KEY and REFERENCES syntax in CREATE TABLE statements. The CHECK clause is parsed but ignored by all storage engines." [73] Note (4): Support for Unicode is new in version 10.0. Note (5): MySQL provides GUI interface through MySQL Workbench.
MySQL (/ ˌ m aɪ ˌ ɛ s ˌ k juː ˈ ɛ l /) [5] is an open-source relational database management system (RDBMS). [5] [6] Its name is a combination of "My", the name of co-founder Michael Widenius's daughter My, [7] and "SQL", the acronym for Structured Query Language.
This can be somewhat mitigated by the CA generating a random component in the certificates it signs, typically the serial number. The CA/Browser Forum has required serial number entropy in its Baseline Requirements Section 7.1 since 2011. [35] As of January 1, 2016, the Baseline Requirements forbid issuance of certificates using SHA-1.

serial numbers, assigned incrementally or sequentially, by a central authority or accepted reference. random numbers, selected from a number space much larger than the maximum (or expected) number of objects to be identified. Although not really unique, some identifiers of this type may be appropriate for identifying objects in many practical ...
The first 6 octets are the number of four-microsecond (μs) units of time that have passed since 1980-01-01 00:00 UTC. The time 2 48 × 4 μs after 1980 started was 2015-09-05 05:58:26.84262 UTC. Thus, the last time at which UUIDs could be generated in this original format was in 2015.
