We also have more to offer you than long password options. And you can do exactly that when you protect your documents with Smallpdf. But to use that technique, you need to be able to input a longer password in the first place. For example, “the1stwomansaidEureka!” is a pretty solid password. One of the best strategies for creating a memorable and easy to type password is to use a phrase. Sure, that sounds like more than enough, but it’s nice to have the option of a longer, more secure password should you want one. This is a perfectly acceptable way to protect your documents, however it is worth noting that the passwords have a limit of 15 characters.
