Although they are similar in many ways and actually toads are a type of frog just it's not that all frogs are toads there are a few differences between the two that are more obvious than others.
How Frogs are Different from Toads
Body
Frogs have a much longer body and longer legs that are built for leaping like that whereas.
Walk
Frogs Leap
Skin
Frogs have the consistently moist skin all around their body.
Eyes
A frog's eyes are much more bulbous.
Frogs do not have those glands so to make up for them they have larger eyes that give them a larger field of vision they actually have nearly a 360 degree field of vision that they utilize without even having to turn their head and that allows them to see predators better than the toads can.
Teeth
Inside of a frog's mouth there's two different types of teeth the maxillary teeth is a small row of teeth that lines the outer edge of their upper jaw. In addition to the maxillary teeth frogs also have vomerine teeth which are two small clusters of projections that are in the roof of their mouth.
Breathe
Frogs always have wet skin because they absorb water through their skin to rehydrate themselves. They also will extract the oxygen from the water on their skin.

Additionally frogs are able to rid themselves of co2 using that same process but in Reverse because of this frogs need to keep their skin continuously what so they prefer to live near bodies of water.
Frogs can also breathe using this method but they will only use their lungs to breathe when they're out of water when they're in the water all oxygen is extracted from the water itself through their skin.
Breeding
Frogs however lays their eggs in large clusters in the water. Sadly in phibian populations including frogs and toads are declining at an alarming rate.
This is because of habitat loss, pollution and chemicals, and man-made structures. Habitat loss is an obvious one humans are transforming native wetlands into buildings and parking lots and other structures and with a lack of wetlands which are essential to the reproduction of frogs and toads they're not able to reproduce.
How Toads are Different from Frogs?
Body
Toads have a much shorter squatter body with shorter legs that are built for hopping and crawling.
Walk
Toads Hop
Skin
Toads have drier and Bumpy skin or some people would describe it as warty skin.
Eyes
Toads eyes are quite a bit more recessed into their skulls and that's because situated behind their eye is a poison gland called a Parotoid gland.
Toads has a Poisnous Gland situated behind their eyes which secrete a poison that irritates the mouths of predators which is the toads defense mechanism.
Teeth
Breathe
Toads have much drier skin and that's because instead of relying on the absorption of water and extraction of oxygen from the water. They will instead get their oxygen from the air by using their lungs when a toad expands its throat.
It creates a bit of a vacuum and it sucks in air through its nose into its throat and then that air gets pushed down into its lungs.
After the oxygen is extracted and exchanged with co2 that co2 goes back into the throat of the toad and they close their throat which pushes that air back out of their nose.
So every time a toad moves its throat in and out it's actually taking breaths of air.
Toads are not reliant on water to absorb through their bodies instead they just use their lungs toads will live further away from bodies of water but they will come back for breeding purposes.
Breeding
Toads lays their eggs in strings but there are a few species of African toads that actually hold on to their eggs within their body and they maternally incubate them until the babies hatch into small tablets.
These few species of toads evolved this adaptation because sources of water in those areas of Africa are few and far between.
In order to better control their eggs humidity or in hydration levels that you just incubate them themselves and then they can make sure they're constantly wet.
